CVE-2025-26466 3 Canonical, Debian, Openbsd 3 Ubuntu Linux, Debian Linux, Openssh 2025-04-10 N/A 5.9 MEDIUM
A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack.
CVE-2009-1270 3 Canonical, Clamav, Debian 3 Ubuntu Linux, Clamav, Debian Linux 2025-04-09 7.8 HIGH N/A
libclamav/untar.c in ClamAV before 0.95 allows remote attackers to cause a denial of service (infinite loop) via a crafted TAR file that causes (1) clamd and (2) clamscan to hang.
CVE-2008-0005 3 Apache, Canonical, Fedoraproject 3 Http Server, Ubuntu Linux, Fedora 2025-04-09 4.3 MEDIUM N/A
mod_proxy_ftp in Apache 2.2.x before 2.2.7-dev, 2.0.x before 2.0.62-dev, and 1.3.x before 1.3.40-dev does not define a charset, which allows remote attackers to conduct cross-site scripting (XSS) attacks using UTF-7 encoding.
CVE-2007-4988 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2025-04-09 6.8 MEDIUM 7.8 HIGH
Sign extension error in the ReadDIBImage function in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted width value in an image file, which triggers an integer overflow and a heap-based buffer overflow.
CVE-2006-6143 2 Canonical, Mit 2 Ubuntu Linux, Kerberos 5 2025-04-09 9.3 HIGH N/A
The RPC library in Kerberos 5 1.4 through 1.4.4, and 1.5 through 1.5.1, as used in Kerberos administration daemon (kadmind) and other products that use this library, calls an uninitialized function pointer in freed memory, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.
CVE-2009-1185 7 Canonical, Debian, Fedoraproject and 4 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2025-04-09 7.2 HIGH N/A
udev before 1.4.1 does not verify whether a NETLINK message originates from kernel space, which allows local users to gain privileges by sending a NETLINK message from user space.
CVE-2007-2442 3 Canonical, Debian, Mit 3 Ubuntu Linux, Debian Linux, Kerberos 5 2025-04-09 10.0 HIGH N/A
The gssrpc__svcauth_gssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup.
CVE-2009-0949 5 Apple, Canonical, Debian and 2 more 7 Cups, Mac Os X, Mac Os X Server and 4 more 2025-04-09 5.0 MEDIUM 7.5 HIGH
The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10 does not properly initialize memory for IPP request packets, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a scheduler request with two consecutive IPP_TAG_UNSUPPORTED tags.
CVE-2008-5506 3 Canonical, Debian, Mozilla 5 Ubuntu Linux, Debian Linux, Firefox and 2 more 2025-04-09 6.8 MEDIUM N/A
Mozilla Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19, Thunderbird 2.x before 2.0.0.19, and SeaMonkey 1.x before 1.1.14 allows remote attackers to bypass the same origin policy by causing the browser to issue an XMLHttpRequest to an attacker-controlled resource that uses a 302 redirect to a resource in a different domain, then reading content from the response, aka "response disclosure."
CVE-2009-3228 3 Canonical, Linux, Redhat 6 Ubuntu Linux, Linux Kernel, Enterprise Linux Desktop and 3 more 2025-04-09 2.1 LOW N/A
The tc_fill_tclass function in net/sched/sch_api.c in the tc subsystem in the Linux kernel 2.4.x before 2.4.37.6 and 2.6.x before 2.6.31-rc9 does not initialize certain (1) tcm__pad1 and (2) tcm__pad2 structure members, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors.
CVE-2008-5513 3 Canonical, Debian, Mozilla 5 Ubuntu Linux, Debian Linux, Firefox and 2 more 2025-04-09 4.3 MEDIUM N/A
Unspecified vulnerability in the session-restore feature in Mozilla Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19 allows remote attackers to bypass the same origin policy, inject content into documents associated with other domains, and conduct cross-site scripting (XSS) attacks via unknown vectors related to restoration of SessionStore data.
CVE-2006-6504 2 Canonical, Mozilla 3 Ubuntu Linux, Firefox, Seamonkey 2025-04-09 9.3 HIGH N/A
Mozilla Firefox 2.x before 2.0.0.1, 1.5.x before 1.5.0.9, and SeaMonkey before 1.0.7 allows remote attackers to execute arbitrary code by appending an SVG comment DOM node to another type of document, which triggers memory corruption.
CVE-2008-3275 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2025-04-09 4.9 MEDIUM 5.5 MEDIUM
The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation in the Linux kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ("overflow" of the UBIFS orphan area) via a series of attempted file creations within deleted directories.
CVE-2009-3232 1 Canonical 1 Ubuntu Linux 2025-04-09 9.3 HIGH N/A
pam-auth-update for PAM, as used in Ubuntu 8.10 and 9.4, and Debian GNU/Linux, does not properly handle an "empty selection" for system authentication modules in certain rare configurations, which causes any attempt to be successful and allows remote attackers to bypass authentication.
CVE-2008-0017 3 Canonical, Debian, Mozilla 4 Ubuntu Linux, Debian Linux, Firefox and 1 more 2025-04-09 9.3 HIGH N/A
The http-index-format MIME type parser (nsDirIndexParser) in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 does not check for an allocation failure, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an HTTP index response with a crafted 200 header, which triggers memory corruption and a buffer overflow.
CVE-2008-1672 2 Canonical, Openssl 2 Ubuntu Linux, Openssl 2025-04-09 4.3 MEDIUM N/A
OpenSSL 0.9.8f and 0.9.8g allows remote attackers to cause a denial of service (crash) via a TLS handshake that omits the Server Key Exchange message and uses "particular cipher suites," which triggers a NULL pointer dereference.
CVE-2009-2287 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-04-09 4.9 MEDIUM N/A
The kvm_arch_vcpu_ioctl_set_sregs function in the KVM in Linux kernel 2.6 before 2.6.30, when running on x86 systems, does not validate the page table root in a KVM_SET_SREGS call, which allows local users to cause a denial of service (crash or hang) via a crafted cr3 value, which triggers a NULL pointer dereference in the gfn_to_rmap function.
CVE-2009-3939 7 Avaya, Canonical, Debian and 4 more 18 Aura Application Enablement Services, Aura Communication Manager, Aura Session Manager and 15 more 2025-04-09 6.6 MEDIUM 7.1 HIGH
The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file.
CVE-2006-5868 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2025-04-09 9.3 HIGH N/A
Multiple buffer overflows in Imagemagick 6.0 before 6.0.6.2, and 6.2 before 6.2.4.5, has unknown impact and user-assisted attack vectors via a crafted SGI image.
CVE-2008-2664 3 Canonical, Debian, Ruby-lang 3 Ubuntu Linux, Debian Linux, Ruby 2025-04-09 7.8 HIGH N/A
The rb_str_format function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2 allows context-dependent attackers to trigger memory corruption via unspecified vectors related to alloca, a different issue than CVE-2008-2662, CVE-2008-2663, and CVE-2008-2725. NOTE: as of 20080624, there has been inconsistent usage of multiple CVE identifiers related to Ruby. The CVE description should be regarded as authoritative, although it is likely to change.
