| CVE-2023-6780 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Glibc, Enterprise Linux | 2024-11-21 | 5.3 Medium |
| An integer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a very long message, leading to an incorrect calculation of the buffer size to store the message, resulting in undefined behavior. This issue affects glibc 2.37 and newer. | ||||
| CVE-2023-6779 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Glibc, Enterprise Linux | 2024-11-21 | 8.2 High |
| An off-by-one heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a message bigger than INT_MAX bytes, leading to an incorrect calculation of the buffer size to store the message, resulting in an application crash. This issue affects glibc 2.37 and newer. | ||||
| CVE-2023-6246 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Glibc, Enterprise Linux | 2024-11-21 | 8.4 High |
| A heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when the openlog function was not called, or called with the ident argument set to NULL, and the program name (the basename of argv[0]) is bigger than 1024 bytes, resulting in an application crash or local privilege escalation. This issue affects glibc 2.36 and newer. | ||||
| CVE-2023-5156 | 2 Gnu, Redhat | 2 Glibc, Enterprise Linux | 2024-11-21 | 7.5 High |
| A flaw was found in the GNU C Library. A recent fix for CVE-2023-4806 introduced the potential for a memory leak, which may result in an application crash. | ||||
| CVE-2023-4949 | 2 Gnu, Xen | 2 Grub, Xen | 2024-11-21 | 8.1 High |
| An attacker with local access to a system (either through a disk or external drive) can present a modified XFS partition to grub-legacy in such a way to exploit a memory corruption in grub’s XFS file system implementation. | ||||
| CVE-2023-4806 | 3 Fedoraproject, Gnu, Redhat | 24 Fedora, Glibc, Codeready Linux Builder Eus and 21 more | 2024-11-21 | 5.9 Medium |
| A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags. | ||||
| CVE-2023-4156 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Gawk, Enterprise Linux | 2024-11-21 | 4.4 Medium |
| A heap out-of-bounds read flaw was found in builtin.c in the gawk package. This issue may lead to a crash and could be used to read sensitive information. | ||||
| CVE-2023-4039 | 1 Gnu | 1 Gcc | 2024-11-21 | 4.8 Medium |
| **DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables. The default behavior when the stack-protector detects an overflow is to terminate your application, resulting in controlled loss of availability. An attacker who can exploit a buffer overflow without triggering the stack-protector might be able to change program flow control to cause an uncontrolled loss of availability or to go further and affect confidentiality or integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by itself. | ||||
| CVE-2023-4001 | 3 Fedoraproject, Gnu, Redhat | 4 Fedora, Grub2, Enterprise Linux and 1 more | 2024-11-21 | 6.8 Medium |
| An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature. An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the "/boot/" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package. | ||||
| CVE-2023-40305 | 1 Gnu | 1 Indent | 2024-11-21 | 5.5 Medium |
| GNU indent 2.2.13 has a heap-based buffer overflow in search_brace in indent.c via a crafted file. | ||||
| CVE-2023-40303 | 1 Gnu | 1 Inetutils | 2024-11-21 | 7.8 High |
| GNU inetutils before 2.5 may allow privilege escalation because of unchecked return values of set*id() family functions in ftpd, rcp, rlogin, rsh, rshd, and uucpd. This is, for example, relevant if the setuid system call fails when a process is trying to drop privileges before letting an ordinary user control the activities of the process. | ||||
| CVE-2023-39130 | 1 Gnu | 1 Gdb | 2024-11-21 | 5.5 Medium |
| GNU gdb (GDB) 13.0.50.20220805-git was discovered to contain a heap buffer overflow via the function pe_as16() at /gdb/coff-pe-read.c. | ||||
| CVE-2023-39129 | 1 Gnu | 1 Gdb | 2024-11-21 | 5.5 Medium |
| GNU gdb (GDB) 13.0.50.20220805-git was discovered to contain a heap use after free via the function add_pe_exported_sym() at /gdb/coff-pe-read.c. | ||||
| CVE-2023-39128 | 1 Gnu | 1 Gdb | 2024-11-21 | 5.5 Medium |
| GNU gdb (GDB) 13.0.50.20220805-git was discovered to contain a stack overflow via the function ada_decode at /gdb/ada-lang.c. | ||||
| CVE-2023-36274 | 1 Gnu | 1 Libredwg | 2024-11-21 | 8.8 High |
| LibreDWG v0.12.5 was discovered to contain a heap buffer overflow via the function bit_write_TF at bits.c. | ||||
| CVE-2023-36273 | 1 Gnu | 1 Libredwg | 2024-11-21 | 8.8 High |
| LibreDWG v0.12.5 was discovered to contain a heap buffer overflow via the function bit_calc_CRC at bits.c. | ||||
| CVE-2023-36272 | 1 Gnu | 1 Libredwg | 2024-11-21 | 8.8 High |
| LibreDWG v0.12.5 was discovered to contain a heap buffer overflow via the function bit_utf8_to_TU at bits.c. | ||||
| CVE-2023-36271 | 1 Gnu | 1 Libredwg | 2024-11-21 | 8.8 High |
| LibreDWG v0.12.5 was discovered to contain a heap buffer overflow via the function bit_wcs2nlen at bits.c. | ||||
| CVE-2023-2789 | 1 Gnu | 1 Cflow | 2024-11-21 | 3.5 Low |
| A vulnerability was found in GNU cflow 1.7. It has been rated as problematic. This issue affects the function func_body/parse_variable_declaration of the file parser.c. The manipulation leads to denial of service. The exploit has been disclosed to the public and may be used. The identifier VDB-229373 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. | ||||
| CVE-2023-2491 | 2 Gnu, Redhat | 5 Emacs, Enterprise Linux, Enterprise Linux Eus and 2 more | 2024-11-21 | 7.8 High |
| A flaw was found in the Emacs text editor. Processing a specially crafted org-mode code with the "org-babel-execute:latex" function in ob-latex.el can result in arbitrary command execution. This CVE exists because of a CVE-2023-28617 security regression for the emacs package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2. | ||||
