An issue was discovered in ZZIPlib 0.13.68. There is a bus error caused by the __zzip_parse_root_directory function of zip.c. Attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
CVE-2018-6869 3 Canonical, Debian, Gdraheim 3 Ubuntu Linux, Debian Linux, Zziplib 2025-07-10 4.3 MEDIUM 6.5 MEDIUM
In ZZIPlib 0.13.68, there is an uncontrolled memory allocation and a crash in the __zzip_parse_root_directory function of zzip/zip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
CVE-2018-6381 2 Canonical, Gdraheim 2 Ubuntu Linux, Zziplib 2025-07-10 4.3 MEDIUM 6.5 MEDIUM
In ZZIPlib 0.13.67, 0.13.66, 0.13.65, 0.13.64, 0.13.63, 0.13.62, 0.13.61, 0.13.60, 0.13.59, 0.13.58, 0.13.57 and 0.13.56 there is a segmentation fault caused by invalid memory access in the zzip_disk_fread function (zzip/mmapped.c) because the size variable is not validated against the amount of file->stored data.
CVE-2018-6540 2 Canonical, Gdraheim 2 Ubuntu Linux, Zziplib 2025-07-10 4.3 MEDIUM 6.5 MEDIUM
In ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address in the zzip_disk_findfirst function of zzip/mmapped.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
CVE-2019-16869 4 Canonical, Debian, Netty and 1 more 5 Ubuntu Linux, Debian Linux, Netty and 2 more 2025-07-07 5.0 MEDIUM 7.5 HIGH
Netty before 4.1.42.Final mishandles whitespace before the colon in HTTP headers (such as a "Transfer-Encoding : chunked" line), which leads to HTTP request smuggling.
CVE-2019-20444 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2025-07-01 6.4 MEDIUM 9.1 CRITICAL
HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold."
CVE-2023-0386 4 Canonical, Debian, Linux and 1 more 13 Ubuntu Linux, Debian Linux, Linux Kernel and 10 more 2025-06-18 N/A 7.8 HIGH
A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system.
CVE-2019-5747 2 Busybox, Canonical 2 Busybox, Ubuntu Linux 2025-06-09 5.0 MEDIUM 7.5 HIGH
An issue was discovered in BusyBox through 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP client, server, and/or relay) might allow a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to assurance of a 4-byte length when decoding DHCP_SUBNET. NOTE: this issue exists because of an incomplete fix for CVE-2018-20679.
CVE-2019-20386 5 Canonical, Fedoraproject, Netapp and 2 more 7 Ubuntu Linux, Fedora, Active Iq Unified Manager and 4 more 2025-06-09 2.1 LOW 2.4 LOW
An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur.
CVE-2019-12900 6 Bzip, Canonical, Debian and 3 more 6 Bzip2, Ubuntu Linux, Debian Linux and 3 more 2025-06-09 7.5 HIGH 9.8 CRITICAL
BZ2_decompress in decompress.c in bzip2 through 1.0.6 has an out-of-bounds write when there are many selectors.
CVE-2018-6954 3 Canonical, Opensuse, Systemd Project 3 Ubuntu Linux, Leap, Systemd 2025-06-09 7.2 HIGH 7.8 HIGH
systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.
CVE-2018-20679 2 Busybox, Canonical 2 Busybox, Ubuntu Linux 2025-06-09 5.0 MEDIUM 7.5 HIGH
An issue was discovered in BusyBox before 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP server, client, and relay) allows a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to verification in udhcp_get_option() in networking/udhcp/common.c that 4-byte options are indeed 4 bytes.
CVE-2018-15688 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2025-06-09 5.8 MEDIUM 8.8 HIGH
A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including 239.
CVE-2018-15687 2 Canonical, Systemd Project 2 Ubuntu Linux, Systemd 2025-06-09 6.9 MEDIUM 7.0 HIGH
A race condition in chown_one() of systemd allows an attacker to cause systemd to set arbitrary permissions on arbitrary files. Affected releases are systemd versions up to and including 239.
CVE-2018-15686 4 Canonical, Debian, Oracle and 1 more 4 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 1 more 2025-06-09 7.2 HIGH 7.8 HIGH
A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239.
