CVE-2025-61154 1 Gnu 1 Libredwg 2026-06-02 N/A 6.5 MEDIUM
Heap buffer overflow vulnerability in LibreDWG versions v0.13.3.7571 up to v0.13.3.7835 allows a crafted DWG file to cause a Denial of Service (DoS) via the function decompress_R2004_section at decode.c.
CVE-2026-3832 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-06-02 N/A 3.7 LOW
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
CVE-2026-42010 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-06-02 N/A 7.1 HIGH
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
CVE-2026-3833 2 Gnu, Redhat 4 Gnutls, Enterprise Linux, Hardened Images and 1 more 2026-06-02 N/A 6.5 MEDIUM
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.
CVE-2026-33845 2 Gnu, Redhat 3 Gnutls, Enterprise Linux, Openshift Container Platform 2026-06-02 N/A 7.5 HIGH
A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
CVE-2009-3555 8 Apache, Canonical, Debian and 5 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2026-05-27 5.8 MEDIUM 9.8 CRITICAL
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue.
CVE-2022-2601 3 Fedoraproject, Gnu, Redhat 8 Fedora, Grub2, Enterprise Linux Eus and 5 more 2026-05-27 N/A 8.6 HIGH
A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism.
CVE-2022-3775 2 Gnu, Redhat 2 Grub2, Enterprise Linux 2026-05-27 N/A 7.1 HIGH
When rendering certain unicode sequences, grub2's font code doesn't proper validate if the informed glyph's width and height is constrained within bitmap size. As consequence an attacker can craft an input which will lead to a out-of-bounds write into grub2's heap, leading to memory corruption and availability issues. Although complex, arbitrary code execution could not be discarded.
CVE-2025-61662 1 Gnu 1 Grub2 2026-05-20 N/A 7.8 HIGH
A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the application to access a memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded.
CVE-2026-6843 2 Gnu, Redhat 3 Nano, Enterprise Linux, Openshift Container Platform 2026-05-20 N/A 5.5 MEDIUM
A flaw was found in nano. A local user could exploit a format string vulnerability in the `statusline()` function. By creating a directory with a name containing `printf` specifiers, the application attempts to display this name, leading to a segmentation fault (SEGV). This results in a Denial of Service (DoS) for the `nano` application.
CVE-2026-6844 2 Gnu, Redhat 4 Binutils, Enterprise Linux, Hardened Images and 1 more 2026-05-20 N/A 5.5 MEDIUM
A flaw was found in the `readelf` utility of the binutils package. A local attacker could exploit two Denial of Service (DoS) vulnerabilities by providing a specially crafted Executable and Linkable Format (ELF) file. One vulnerability, a resource exhaustion (CWE-400), can lead to an out-of-memory condition. The other, a null pointer dereference (CWE-476), can cause a segmentation fault. Both issues can result in the `readelf` utility becoming unresponsive or crashing, leading to a denial of service.
CVE-2026-6845 2 Gnu, Redhat 4 Binutils, Enterprise Linux, Hardened Images and 1 more 2026-05-20 N/A 5.0 MEDIUM
A flaw was found in binutils, specifically within the `readelf` utility. This vulnerability allows a local attacker to cause a Denial of Service (DoS) by tricking a user into processing a specially crafted Executable and Linkable Format (ELF) file. The exploitation of this flaw can lead to the system becoming unresponsive due to excessive resource consumption or a program crash.
CVE-2026-6846 2 Gnu, Redhat 4 Binutils, Enterprise Linux, Hardened Images and 1 more 2026-05-20 N/A 7.8 HIGH
A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable.
CVE-2017-17440 1 Gnu 1 Libextractor 2026-05-13 4.3 MEDIUM 6.5 MEDIUM
GNU Libextractor 1.6 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted GIF, IT (Impulse Tracker), NSFE, S3M (Scream Tracker 3), SID, or XM (eXtended Module) file, as demonstrated by the EXTRACTOR_xm_extract_method function in plugins/xm_extractor.c.
CVE-2017-15225 1 Gnu 1 Binutils 2026-05-13 4.3 MEDIUM 5.5 MEDIUM
_bfd_dwarf2_cleanup_debug_info in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, allows remote attackers to cause a denial of service (memory leak) via a crafted ELF file.
CVE-2014-9939 1 Gnu 1 Binutils 2026-05-13 7.5 HIGH 9.8 CRITICAL
ihex.c in GNU Binutils before 2.26 contains a stack buffer overflow when printing bad bytes in Intel Hex objects.
CVE-2016-4487 1 Gnu 1 Libiberty 2026-05-13 4.3 MEDIUM 5.5 MEDIUM
Use-after-free vulnerability in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, related to "btypevec."
CVE-2017-13728 1 Gnu 1 Ncurses 2026-05-13 4.3 MEDIUM 7.5 HIGH
There is an infinite loop in the next_char function in comp_scan.c in ncurses 6.0, related to libtic. A crafted input will lead to a remote denial of service attack.
CVE-2017-14482 2 Debian, Gnu 2 Debian Linux, Emacs 2026-05-13 6.8 MEDIUM 8.8 HIGH
GNU Emacs before 25.3 allows remote attackers to execute arbitrary code via email with crafted "Content-Type: text/enriched" data containing an x-display XML element that specifies execution of shell commands, related to an unsafe text/enriched extension in lisp/textmodes/enriched.el, and unsafe Gnus support for enriched and richtext inline MIME objects in lisp/gnus/mm-view.el. In particular, an Emacs user can be instantly compromised by reading a crafted email message (or Usenet news article).
CVE-2017-12960 1 Gnu 1 Pspp 2026-05-13 5.0 MEDIUM 7.5 HIGH
There is a reachable assertion abort in the function dict_rename_var() in data/dictionary.c of the libpspp library in GNU PSPP before 1.0.1 that will lead to remote denial of service.
