CVE-2023-6779 2 Fedoraproject, Gnu 2 Fedora, Glibc 2024-11-21 N/A 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 2 Fedoraproject, Gnu 2 Fedora, Glibc 2024-11-21 N/A 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-2023-5981 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gnutls, Linux 2024-11-21 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-2023-5156 2 Gnu, Redhat 2 Glibc, Enterprise Linux 2024-11-21 N/A 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 N/A 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-2023-4693 2 Gnu, Redhat 2 Grub2, Enterprise Linux 2024-11-21 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 2024-11-21 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-2023-4156 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gawk, Enterprise Linux 2024-11-21 N/A 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-2023-4001 3 Fedoraproject, Gnu, Redhat 3 Fedora, Grub2, Enterprise Linux 2024-11-21 N/A 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 N/A 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 N/A 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 N/A 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 N/A 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 N/A 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-2023-36273 1 Gnu 1 Libredwg 2024-11-21 N/A 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-2023-2789 1 Gnu 1 Cflow 2024-11-21 2.7 LOW 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-2023-29491 1 Gnu 1 Ncurses 2024-11-21 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-2023-27371 1 Gnu 1 Libmicrohttpd 2024-11-21 N/A 5.9 MEDIUM
GNU libmicrohttpd before 0.9.76 allows remote DoS (Denial of Service) due to improper parsing of a multipart/form-data boundary in the postprocessor.c MHD_create_post_processor() method. This allows an attacker to remotely send a malicious HTTP POST packet that includes one or more '\0' bytes in a multipart/form-data boundary field, which - assuming a specific heap layout - will result in an out-of-bounds read and a crash in the find_boundary() function.
CVE-2023-26157 1 Gnu 1 Libredwg 2024-11-21 N/A 5.5 MEDIUM
Versions of the package libredwg before 0.12.5.6384 are vulnerable to Denial of Service (DoS) due to an out-of-bounds read involving section->num_pages in decode_r2007.c.
CVE-2023-25588 1 Gnu 1 Binutils 2024-11-21 N/A 4.7 MEDIUM
A flaw was found in Binutils. The field `the_bfd` of `asymbol`struct is uninitialized in the `bfd_mach_o_get_synthetic_symtab` function, which may lead to an application crash and local denial of service.
