CVE-2023-0386 5 Canonical, Debian, Linux and 2 more 16 Ubuntu Linux, Debian Linux, Linux Kernel and 13 more 2025-07-30 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-2023-4911 6 Canonical, Debian, Fedoraproject and 3 more 40 Ubuntu Linux, Debian Linux, Fedora and 37 more 2025-07-30 7.8 High
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2022-2586 3 Canonical, Linux, Redhat 5 Ubuntu Linux, Linux Kernel, Enterprise Linux and 2 more 2025-07-30 5.3 Medium
It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted.
CVE-2025-26466 4 Canonical, Debian, Openbsd and 1 more 5 Ubuntu Linux, Debian Linux, Openssh and 2 more 2025-07-25 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-2024-6387 9 Amazon, Canonical, Debian and 6 more 24 Linux 2023, Ubuntu Linux, Debian Linux and 21 more 2025-07-24 8.1 High
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.
CVE-2023-3567 3 Canonical, Linux, Redhat 5 Ubuntu Linux, Linux Kernel, Enterprise Linux and 2 more 2025-07-23 7.1 High
A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information.
CVE-2025-32463 6 Canonical, Debian, Opensuse and 3 more 8 Ubuntu Linux, Debian Linux, Leap and 5 more 2025-07-22 9.3 Critical
Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option.
CVE-2019-13454 5 Canonical, Debian, Imagemagick and 2 more 5 Ubuntu Linux, Debian Linux, Imagemagick and 2 more 2025-07-11 6.5 Medium
ImageMagick 7.0.1-0 to 7.0.8-54 Q16 allows Division by Zero in RemoveDuplicateLayers in MagickCore/layer.c.
CVE-2018-6381 2 Canonical, Gdraheim 2 Ubuntu Linux, Zziplib 2025-07-10 N/A
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-2018-6484 2 Canonical, Gdraheim 2 Ubuntu Linux, Zziplib 2025-07-10 N/A
In ZZIPlib 0.13.67, there is a memory alignment error and bus error in the __zzip_fetch_disk_trailer function of zzip/zip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
CVE-2018-6540 2 Canonical, Gdraheim 2 Ubuntu Linux, Zziplib 2025-07-10 N/A
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-2018-6869 3 Canonical, Debian, Gdraheim 3 Ubuntu Linux, Debian Linux, Zziplib 2025-07-10 N/A
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-2018-6541 3 Canonical, Gdraheim, Redhat 3 Ubuntu Linux, Zziplib, Enterprise Linux 2025-07-10 N/A
In ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address (when handling disk64_trailer local entries) in __zzip_fetch_disk_trailer (zzip/zip.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
CVE-2018-7726 3 Canonical, Gdraheim, Redhat 6 Ubuntu Linux, Zziplib, Enterprise Linux and 3 more 2025-07-10 N/A
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-2018-7725 3 Canonical, Gdraheim, Redhat 6 Ubuntu Linux, Zziplib, Enterprise Linux and 3 more 2025-07-10 N/A
An issue was discovered in ZZIPlib 0.13.68. An invalid memory address dereference was discovered in zzip_disk_fread in mmapped.c. The vulnerability causes an application crash, which leads to denial of service.
CVE-2019-16869 4 Canonical, Debian, Netty and 1 more 14 Ubuntu Linux, Debian Linux, Netty and 11 more 2025-07-07 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 19 Ubuntu Linux, Debian Linux, Fedora and 16 more 2025-07-01 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-2019-5747 2 Busybox, Canonical 2 Busybox, Ubuntu Linux 2025-06-09 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.
