CVE-2025-26465 4 Debian, Netapp, Openbsd and 1 more 6 Debian Linux, Active Iq Unified Manager, Ontap and 3 more 2025-10-23 N/A 6.8 MEDIUM
A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high.
CVE-2025-6021 2 Redhat, Xmlsoft 20 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 17 more 2025-10-22 N/A 7.5 HIGH
A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
CVE-2025-5914 2 Libarchive, Redhat 3 Libarchive, Enterprise Linux, Openshift Container Platform 2025-10-22 N/A 7.3 HIGH
A vulnerability has been identified in the libarchive library, specifically within the archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, enabling an attacker to execute arbitrary code or cause a denial-of-service condition.
CVE-2014-7169 17 Apple, Arista, Canonical and 14 more 85 Mac Os X, Eos, Ubuntu Linux and 82 more 2025-10-22 10.0 HIGH 9.8 CRITICAL
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.
CVE-2014-6271 17 Apple, Arista, Canonical and 14 more 85 Mac Os X, Eos, Ubuntu Linux and 82 more 2025-10-22 10.0 HIGH 9.8 CRITICAL
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.
CVE-2014-0196 7 Canonical, Debian, F5 and 4 more 30 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 27 more 2025-10-22 6.9 MEDIUM 5.5 MEDIUM
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings.
CVE-2013-2251 5 Apache, Fujitsu, Microsoft and 2 more 21 Archiva, Struts, Gp-s and 18 more 2025-10-22 9.3 HIGH 9.8 CRITICAL
Apache Struts 2.0.0 through 2.3.15 allows remote attackers to execute arbitrary OGNL expressions via a parameter with a crafted (1) action:, (2) redirect:, or (3) redirectAction: prefix.
CVE-2010-3904 6 Canonical, Linux, Opensuse and 3 more 8 Ubuntu Linux, Linux Kernel, Opensuse and 5 more 2025-10-22 7.2 HIGH 7.8 HIGH
The rds_page_copy_user function in net/rds/page.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel before 2.6.36 does not properly validate addresses obtained from user space, which allows local users to gain privileges via crafted use of the sendmsg and recvmsg system calls.
CVE-2010-1871 2 Netapp, Redhat 5 Oncommand Balance, Oncommand Insight, Oncommand Unified Manager and 2 more 2025-10-22 6.8 MEDIUM 8.8 HIGH
JBoss Seam 2 (jboss-seam2), as used in JBoss Enterprise Application Platform 4.3.0 for Red Hat Linux, does not properly sanitize inputs for JBoss Expression Language (EL) expressions, which allows remote attackers to execute arbitrary code via a crafted URL. NOTE: this is only a vulnerability when the Java Security Manager is not properly configured.
CVE-2022-0847 7 Fedoraproject, Linux, Netapp and 4 more 39 Fedora, Linux Kernel, H300e and 36 more 2025-10-22 7.2 HIGH 7.8 HIGH
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.
CVE-2021-4034 7 Canonical, Oracle, Polkit Project and 4 more 31 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 28 more 2025-10-22 7.2 HIGH 7.8 HIGH
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.
CVE-2021-40438 11 Apache, Broadcom, Debian and 8 more 40 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 37 more 2025-10-22 6.8 MEDIUM 9.0 CRITICAL
A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2021-3560 4 Canonical, Debian, Polkit Project and 1 more 7 Ubuntu Linux, Debian Linux, Polkit and 4 more 2025-10-22 7.2 HIGH 7.8 HIGH
It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2019-8720 3 Redhat, Webkitgtk, Wpewebkit 24 Codeready Linux Builder, Codeready Linux Builder Eus, Codeready Linux Builder For Arm64 Eus and 21 more 2025-10-22 N/A 8.8 HIGH
A vulnerability was found in WebKit. The flaw is triggered when processing maliciously crafted web content that may lead to arbitrary code execution. Improved memory handling addresses the multiple memory corruption issues.
CVE-2019-13272 6 Canonical, Debian, Fedoraproject and 3 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2025-10-22 7.2 HIGH 7.8 HIGH
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.
CVE-2019-11043 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2025-10-22 7.5 HIGH 8.7 HIGH
In PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24 and 7.3.x below 7.3.11 in certain configurations of FPM setup it is possible to cause FPM module to write past allocated buffers into the space reserved for FCGI protocol data, thus opening the possibility of remote code execution.
CVE-2019-0211 8 Apache, Canonical, Debian and 5 more 27 Http Server, Ubuntu Linux, Debian Linux and 24 more 2025-10-22 7.2 HIGH 7.8 HIGH
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected.
CVE-2018-14667 1 Redhat 2 Enterprise Linux, Richfaces 2025-10-22 7.5 HIGH 9.8 CRITICAL
The RichFaces Framework 3.X through 3.3.4 is vulnerable to Expression Language (EL) injection via the UserResource resource. A remote, unauthenticated attacker could exploit this to execute arbitrary code using a chain of java serialized objects via org.ajax4jsf.resource.UserResource$UriData.
CVE-2017-1000253 3 Centos, Linux, Redhat 3 Centos, Linux Kernel, Enterprise Linux 2025-10-22 7.2 HIGH 7.8 HIGH
Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat. With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base. Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the "gap" between the stack and the binary.
CVE-2016-9079 5 Debian, Microsoft, Mozilla and 2 more 11 Debian Linux, Windows, Firefox and 8 more 2025-10-22 5.0 MEDIUM 7.5 HIGH
A use-after-free vulnerability in SVG Animation has been discovered. An exploit built on this vulnerability has been discovered in the wild targeting Firefox and Tor Browser users on Windows. This vulnerability affects Firefox < 50.0.2, Firefox ESR < 45.5.1, and Thunderbird < 45.5.1.
