CVE-2024-45777 2 Gnu, Redhat 3 Grub2, Enterprise Linux, Openshift 2025-11-11 N/A 6.7 MEDIUM
A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in grub_gettext_getstr_from_position() may overflow, leading to a Out-of-bound write. This issue can be leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the circumvention of secure boot protections.
CVE-2025-32990 2 Gnu, Redhat 3 Gnutls, Enterprise Linux, Openshift Container Platform 2025-11-06 N/A 6.5 MEDIUM
A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.
CVE-2025-32989 2 Gnu, Redhat 3 Gnutls, Enterprise Linux, Openshift Container Platform 2025-11-06 N/A 5.3 MEDIUM
A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly.
CVE-2025-32988 2 Gnu, Redhat 3 Gnutls, Enterprise Linux, Openshift Container Platform 2025-11-06 N/A 6.5 MEDIUM
A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior.
CVE-2025-11839 1 Gnu 1 Binutils 2025-11-06 1.7 LOW 3.3 LOW
A security flaw has been discovered in GNU Binutils 2.45. Impacted is the function tg_tag_type of the file prdbg.c. Performing manipulation results in unchecked return value. The attack needs to be approached locally. The exploit has been released to the public and may be exploited.
CVE-2023-4911 6 Canonical, Debian, Fedoraproject and 3 more 38 Ubuntu Linux, Debian Linux, Fedora and 35 more 2025-11-06 N/A 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-2024-0911 1 Gnu 1 Indent 2025-11-04 N/A 5.5 MEDIUM
A flaw was found in indent, a program for formatting C code. This issue may allow an attacker to trick a user into processing a specially crafted file to trigger a heap-based buffer overflow, causing the application to crash.
CVE-2023-5981 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gnutls, Linux 2025-11-04 N/A 5.9 MEDIUM
A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.
CVE-2023-4693 2 Gnu, Redhat 2 Grub2, Enterprise Linux 2025-11-04 N/A 5.3 MEDIUM
An out-of-bounds read flaw was found on grub2's NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack allows sensitive data cached in memory or EFI variable values to be leaked, presenting a high Confidentiality risk.
CVE-2023-4692 2 Gnu, Redhat 2 Grub2, Enterprise Linux 2025-11-04 N/A 7.5 HIGH
An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved.
CVE-2024-0684 1 Gnu 1 Coreutils 2025-11-04 N/A 5.5 MEDIUM
A flaw was found in the GNU coreutils "split" program. A heap overflow with user-controlled data of multiple hundred bytes in length could occur in the line_bytes_split() function, potentially leading to an application crash and denial of service.
CVE-2023-39804 1 Gnu 1 Tar 2025-11-04 N/A 6.2 MEDIUM
In GNU tar before 1.35, mishandled extension attributes in a PAX archive can lead to an application crash in xheader.c.
CVE-2023-29491 1 Gnu 1 Ncurses 2025-11-04 N/A 7.8 HIGH
ncurses before 6.4 20230408, when used by a setuid application, allows local users to trigger security-relevant memory corruption via malformed data in a terminfo database file that is found in $HOME/.terminfo or reached via the TERMINFO or TERM environment variable.
CVE-2022-3715 2 Gnu, Redhat 2 Bash, Enterprise Linux 2025-11-03 N/A 7.8 HIGH
A flaw was found in the bash package, where a heap-buffer overflow can occur in valid parameter_transform. This issue may lead to memory problems.
CVE-2010-4756 1 Gnu 1 Glibc 2025-11-03 4.0 MEDIUM N/A
The glob implementation in the GNU C Library (aka glibc or libc6) allows remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different vulnerability than CVE-2010-2632.
CVE-2024-53920 1 Gnu 1 Emacs 2025-11-03 N/A 7.8 HIGH
In elisp-mode.el in GNU Emacs before 30.1, a user who chooses to invoke elisp-completion-at-point (for code completion) on untrusted Emacs Lisp source code can trigger unsafe Lisp macro expansion that allows attackers to execute arbitrary code. (This unsafe expansion also occurs if a user chooses to enable on-the-fly diagnosis that byte compiles untrusted Emacs Lisp source code.)
CVE-2023-28617 1 Gnu 1 Org Mode 2025-11-03 N/A 7.8 HIGH
org-babel-execute:latex in ob-latex.el in Org Mode through 9.6.1 for GNU Emacs allows attackers to execute arbitrary commands via a file name or directory name that contains shell metacharacters.
CVE-2025-4802 1 Gnu 1 Glibc 2025-11-03 N/A 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-2025-45582 1 Gnu 1 Tar 2025-11-02 N/A 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). NOTE: the official GNU Tar manual has an otherwise-empty directory for each "tar xf" in its Security Rules of Thumb; however, third-party advice leads users to run "tar xf" more than once into the same directory.
CVE-2025-11840 1 Gnu 1 Binutils 2025-10-23 1.7 LOW 3.3 LOW
A weakness has been identified in GNU Binutils 2.45. The affected element is the function vfinfo of the file ldmisc.c. Executing manipulation can lead to out-of-bounds read. The attack can only be executed locally. The exploit has been made available to the public and could be exploited. This patch is called 16357. It is best practice to apply a patch to resolve this issue.
