| CVE-2026-1584 | 2 Gnu, Redhat | 5 Gnutls, Enterprise Linux, Hardened Images and 2 more | 2026-05-03 | 7.5 High |
| A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and resulting in a remote Denial of Service (DoS) condition. | ||||
| CVE-2026-5928 | 2 Gnu, The Gnu C Library | 2 Glibc, Glibc | 2026-04-30 | 7.5 High |
| Calling the ungetwc function on a FILE stream with wide characters encoded in a character set that has overlaps between its single byte and multi-byte character encodings, in the GNU C Library version 2.43 or earlier, may result in an attempt to read bytes before an allocated buffer, potentially resulting in unintentional disclosure of neighboring data in the heap, or a program crash. A bug in the wide character pushback implementation (_IO_wdefault_pbackfail in libio/wgenops.c) causes ungetwc() to operate on the regular character buffer (fp->_IO_read_ptr) instead of the actual wide-stream read pointer (fp->_wide_data->_IO_read_ptr). The program crash may happen in cases where fp->_IO_read_ptr is not initialized and hence points to NULL. The buffer under-read requires a special situation where the input character encoding is such that there are overlaps between single byte representations and multibyte representations in that encoding, resulting in spurious matches. The spurious match case is not possible in the standard Unicode character sets. | ||||
| CVE-2026-0861 | 1 Gnu | 1 Glibc | 2026-04-29 | 8.4 High |
| Passing too large an alignment to the memalign suite of functions (memalign, posix_memalign, aligned_alloc) in the GNU C Library version 2.30 to 2.42 may result in an integer overflow, which could consequently result in a heap corruption. Note that the attacker must have control over both, the size as well as the alignment arguments of the memalign function to be able to exploit this. The size parameter must be close enough to PTRDIFF_MAX so as to overflow size_t along with the large alignment argument. This limits the malicious inputs for the alignment for memalign to the range [1<<62+ 1, 1<<63] and exactly 1<<63 for posix_memalign and aligned_alloc. Typically the alignment argument passed to such functions is a known constrained quantity (e.g. page size, block size, struct sizes) and is not attacker controlled, because of which this may not be easily exploitable in practice. An application bug could potentially result in the input alignment being too large, e.g. due to a different buffer overflow or integer overflow in the application or its dependent libraries, but that is again an uncommon usage pattern given typical sources of alignments. | ||||
| CVE-2026-40556 | 1 Gnu | 1 Nano | 2026-04-29 | N/A |
| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. | ||||
| CVE-2026-5450 | 2 Gnu, The Gnu C Library | 2 Glibc, Glibc | 2026-04-23 | 9.8 Critical |
| Calling the scanf family of functions with a %mc (malloc'd character match) in the GNU C Library version 2.7 to version 2.43 with a format width specifier with an explicit width greater than 1024 could result in a one byte heap buffer overflow. | ||||
| CVE-2009-1214 | 1 Gnu | 1 Screen | 2026-04-23 | N/A |
| GNU screen 4.0.3 creates the /tmp/screen-exchange temporary file with world-readable permissions, which might allow local users to obtain sensitive session information. | ||||
| CVE-2009-3490 | 2 Gnu, Redhat | 2 Wget, Enterprise Linux | 2026-04-23 | N/A |
| GNU Wget before 1.12 does not properly handle a '\0' character in a domain name in the Common Name field of an X.509 certificate, which allows man-in-the-middle remote attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. | ||||
| CVE-2009-4029 | 2 Gnu, Redhat | 2 Automake, Enterprise Linux | 2026-04-23 | N/A |
| The (1) dist or (2) distcheck rules in GNU Automake 1.11.1, 1.10.3, and release branches branch-1-4 through branch-1-9, when producing a distribution tarball for a package that uses Automake, assign insecure permissions (777) to directories in the build tree, which introduces a race condition that allows local users to modify the contents of package files, introduce Trojan horse programs, or conduct other attacks before the build is complete. | ||||
| CVE-2009-4128 | 1 Gnu | 1 Grub 2 | 2026-04-23 | N/A |
| GNU GRand Unified Bootloader (GRUB) 2 1.97 only compares the submitted portion of a password with the actual password, which makes it easier for physically proximate attackers to conduct brute force attacks and bypass authentication by submitting a password whose length is 1. | ||||
| CVE-2008-2142 | 1 Gnu | 2 Emacs, Xemacs | 2026-04-23 | N/A |
| Emacs 21 and XEmacs automatically load and execute .flc (fast lock) files that are associated with other files that are edited within Emacs, which allows user-assisted attackers to execute arbitrary code. | ||||
| CVE-2008-1950 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2026-04-23 | N/A |
| Integer signedness error in the _gnutls_ciphertext2compressed function in lib/gnutls_cipher.c in libgnutls in GnuTLS before 2.2.4 allows remote attackers to cause a denial of service (buffer over-read and crash) via a certain integer value in the Random field in an encrypted Client Hello message within a TLS record with an invalid Record Length, which leads to an invalid cipher padding length, aka GNUTLS-SA-2008-1-3. | ||||
| CVE-2008-1687 | 1 Gnu | 1 M4 | 2026-04-23 | N/A |
| The (1) maketemp and (2) mkstemp builtin functions in GNU m4 before 1.4.11 do not quote their output when a file is created, which might allow context-dependent attackers to trigger a macro expansion, leading to unspecified use of an incorrect filename. | ||||
| CVE-2007-3048 | 1 Gnu | 1 Screen | 2026-04-23 | N/A |
| GNU screen 4.0.3 allows local users to unlock the screen via a CTRL-C sequence at the password prompt. NOTE: multiple third parties report inability to reproduce this issue | ||||
| CVE-2006-4573 | 1 Gnu | 1 Screen | 2026-04-23 | N/A |
| Multiple unspecified vulnerabilities in the "utf8 combining characters handling" (utf8_handle_comb function in encoding.c) in screen before 4.0.3 allows user-assisted attackers to cause a denial of service (crash or hang) via certain UTF8 sequences. | ||||
| CVE-2008-1948 | 2 Gnu, Redhat | 2 Gnutls, Enterprise Linux | 2026-04-23 | N/A |
| The _gnutls_server_name_recv_params function in lib/ext_server_name.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 does not properly calculate the number of Server Names in a TLS 1.0 Client Hello message during extension handling, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a zero value for the length of Server Names, which leads to a buffer overflow in session resumption data in the pack_security_parameters function, aka GNUTLS-SA-2008-1-1. | ||||
| CVE-2010-0002 | 1 Gnu | 1 Bash | 2026-04-23 | N/A |
| The /etc/profile.d/60alias.sh script in the Mandriva bash package for Bash 2.05b, 3.0, 3.2, 3.2.48, and 4.0 enables the --show-control-chars option in LS_OPTIONS, which allows local users to send escape sequences to terminal emulators, or hide the existence of a file, via a crafted filename. | ||||
| CVE-2009-2409 | 4 Gnu, Mozilla, Openssl and 1 more | 7 Gnutls, Network Security Services, Openssl and 4 more | 2026-04-23 | N/A |
| The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large. | ||||
| CVE-2006-6097 | 2 Gnu, Redhat | 2 Tar, Enterprise Linux | 2026-04-23 | N/A |
| GNU tar 1.16 and 1.15.1, and possibly other versions, allows user-assisted attackers to overwrite arbitrary files via a tar file that contains a GNUTYPE_NAMES record with a symbolic link, which is not properly handled by the extract_archive function in extract.c and extract_mangle function in mangle.c, a variant of CVE-2002-1216. | ||||
| CVE-2009-1416 | 1 Gnu | 1 Gnutls | 2026-04-23 | N/A |
| lib/gnutls_pk.c in libgnutls in GnuTLS 2.5.0 through 2.6.5 generates RSA keys stored in DSA structures, instead of the intended DSA keys, which might allow remote attackers to spoof signatures on certificates or have unspecified other impact by leveraging an invalid DSA key. | ||||
| CVE-2008-4989 | 7 Canonical, Debian, Fedoraproject and 4 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2026-04-23 | 5.9 Medium |
| The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN). | ||||
