CVE-2025-0684 2 Gnu, Redhat 3 Grub2, Enterprise Linux, Openshift 2025-07-28 6.4 Medium
A flaw was found in grub2. When performing a symlink lookup from a reiserfs filesystem, grub's reiserfs fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the grub_reiserfs_read_symlink() will call grub_reiserfs_read_real() with a overflown length parameter, leading to a heap based out-of-bounds write during data reading. This flaw may be leveraged to corrupt grub's internal critical data and can result in arbitrary code execution, by-passing secure boot protections.
CVE-2025-4802 2 Gnu, Redhat 7 Glibc, Discovery, Enterprise Linux and 4 more 2025-07-26 7.8 High
Untrusted LD_LIBRARY_PATH environment variable vulnerability in the GNU C Library version 2.27 to 2.38 allows attacker controlled loading of dynamically shared library in statically compiled setuid binaries that call dlopen (including internal dlopen calls after setlocale or calls to NSS functions such as getaddrinfo).
CVE-2025-8058 1 Gnu 1 Glibc 2025-07-25 4.2 Medium
The regcomp function in the GNU C library version from 2.4 to 2.41 is subject to a double free if some previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library.
CVE-2025-47229 1 Gnu 1 Pspp 2025-07-18 2.9 Low
libpspp-core.a in GNU PSPP through 2.0.1 allows attackers to cause a denial of service (var_set_leave_quiet assertion failure and application exit) via crafted input data, such as data that triggers a call from src/data/dictionary.c code into src/data/variable.c code.
CVE-2025-48188 1 Gnu 1 Pspp 2025-07-17 2.9 Low
libpspp-core.a in GNU PSPP through 2.0.1 has an incorrect call from fill_buffer (in data/encrypted-file.c) to the Gnulib rijndaelDecrypt function, leading to a heap-based buffer over-read.
CVE-2025-45582 1 Gnu 1 Tar 2025-07-17 4.1 Medium
GNU Tar through 1.35 allows file overwrite via directory traversal in crafted TAR archives, with a certain two-step process. First, the victim must extract an archive that contains a ../ symlink to a critical directory. Second, the victim must extract an archive that contains a critical file, specified via a relative pathname that begins with the symlink name and ends with that critical file's name. Here, the extraction follows the symlink and overwrites the critical file. This bypasses the protection mechanism of "Member name contains '..'" that would occur for a single TAR archive that attempted to specify the critical file via a ../ approach. For example, the first archive can contain "x -> ../../../../../home/victim/.ssh" and the second archive can contain x/authorized_keys. This can affect server applications that automatically extract any number of user-supplied TAR archives, and were relying on the blocking of traversal. This can also affect software installation processes in which "tar xf" is run more than once (e.g., when installing a package can automatically install two dependencies that are set up as untrusted tarballs instead of official packages).
CVE-2025-52993 2 Gnu, Nixos 2 Guix, Nix 2025-07-13 5.6 Medium
A race condition in the Nix, Lix, and Guix package managers enables changing the ownership of arbitrary files to the UID and GID of the build user (e.g., nixbld* or guixbuild*). This affects Nix before 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix before 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b.
CVE-2024-5742 2 Gnu, Redhat 2 Nano, Enterprise Linux 2025-07-05 6.7 Medium
A vulnerability was found in GNU Nano that allows a possible privilege escalation through an insecure temporary file. If Nano is killed while editing, a file it saves to an emergency file with the permissions of the running user provides a window of opportunity for attackers to escalate privileges through a malicious symlink.
CVE-2025-0678 2 Gnu, Redhat 4 Grub2, Enterprise Linux, Openshift and 1 more 2025-07-05 7.8 High
A flaw was found in grub2. When reading data from a squash4 filesystem, grub's squash4 fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciously crafted filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the direct_read() will perform a heap based out-of-bounds write during data reading. This flaw may be leveraged to corrupt grub's internal critical data and may result in arbitrary code execution, by-passing secure boot protections.
CVE-2023-4527 4 Fedoraproject, Gnu, Netapp and 1 more 32 Fedora, Glibc, H300s and 29 more 2025-06-24 6.5 Medium
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.
CVE-2025-5244 1 Gnu 1 Binutils 2025-06-24 5.3 Medium
A vulnerability was found in GNU Binutils up to 2.44. It has been rated as critical. Affected by this issue is the function elf_gc_sweep of the file bfd/elflink.c of the component ld. The manipulation leads to memory corruption. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. Upgrading to version 2.45 is able to address this issue. It is recommended to upgrade the affected component.
CVE-2025-5245 1 Gnu 1 Binutils 2025-06-24 5.3 Medium
A vulnerability classified as critical has been found in GNU Binutils up to 2.44. This affects the function debug_type_samep of the file /binutils/debug.c of the component objdump. The manipulation leads to memory corruption. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue.
CVE-2024-56737 1 Gnu 1 Grub2 2025-06-24 8.8 High
GNU GRUB (aka GRUB2) through 2.12 has a heap-based buffer overflow in fs/hfs.c via crafted sblock data in an HFS filesystem.
CVE-2024-56738 1 Gnu 1 Grub2 2025-06-24 5.3 Medium
GNU GRUB (aka GRUB2) through 2.12 does not use a constant-time algorithm for grub_crypto_memcmp and thus allows side-channel attacks.
CVE-2025-46802 1 Gnu 1 Screen 2025-06-23 6 Medium
For a short time they PTY is set to mode 666, allowing any user on the system to connect to the screen session.
CVE-2025-46803 1 Gnu 1 Screen 2025-06-23 5 Medium
The default mode of pseudo terminals (PTYs) allocated by Screen was changed from 0620 to 0622, thereby allowing anyone to write to any Screen PTYs in the system.
CVE-2025-46804 1 Gnu 1 Screen 2025-06-23 3.3 Low
A minor information leak when running Screen with setuid-root privileges allows unprivileged users to deduce information about a path that would otherwise not be available. Affected are older Screen versions, as well as version 5.0.0.
CVE-2024-36600 1 Gnu 1 Libcdio 2025-06-20 8.4 High
Buffer Overflow Vulnerability in libcdio v2.1.0 allows an attacker to execute arbitrary code via a crafted ISO 9660 image file.
CVE-2024-33599 4 Debian, Gnu, Netapp and 1 more 20 Debian Linux, Glibc, H300s and 17 more 2025-06-18 8.1 High
nscd: Stack-based buffer overflow in netgroup cache If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted by client requests then a subsequent client request for netgroup data may result in a stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.
CVE-2024-33600 4 Debian, Gnu, Netapp and 1 more 27 Debian Linux, Glibc, Active Iq Unified Manager and 24 more 2025-06-18 5.9 Medium
nscd: Null pointer crashes after notfound response If the Name Service Cache Daemon's (nscd) cache fails to add a not-found netgroup response to the cache, the client request can result in a null pointer dereference. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.
