CVE-2002-1146 1 Gnu 1 Glibc 2025-04-03 5.0 MEDIUM N/A
The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, use the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary ("read buffer overflow"), allowing remote attackers to cause a denial of service (crash).
CVE-2003-0028 10 Cray, Freebsd, Gnu and 7 more 13 Unicos, Freebsd, Glibc and 10 more 2025-04-03 7.5 HIGH N/A
Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391.
CVE-2002-1265 3 Apple, Gnu, Sgi 4 Mac Os X, Mac Os X Server, Glibc and 1 more 2025-04-03 5.0 MEDIUM N/A
The Sun RPC functionality in multiple libc implementations does not provide a time-out mechanism when reading data from TCP connections, which allows remote attackers to cause a denial of service (hang).
CVE-2003-0859 5 Gnu, Intel, Quagga and 2 more 7 Glibc, Zebra, Ia64 and 4 more 2025-04-03 4.9 MEDIUM N/A
The getifaddrs function in GNU libc (glibc) 2.2.4 and earlier allows local users to cause a denial of service by sending spoofed messages as other users to the kernel netlink interface.
CVE-2002-0684 2 Gnu, Isc 2 Glibc, Bind 2025-04-03 7.5 HIGH N/A
Buffer overflow in DNS resolver functions that perform lookup of network names and addresses, as used in BIND 4.9.8 and ported to glibc 2.2.5 and earlier, allows remote malicious DNS servers to execute arbitrary code through a subroutine used by functions such as getnetbyname and getnetbyaddr.
CVE-2023-25139 1 Gnu 1 Glibc 2025-03-26 N/A 9.8 CRITICAL
sprintf in the GNU C Library (glibc) 2.37 has a buffer overflow (out-of-bounds write) in some situations with a correct buffer size. This is unrelated to CWE-676. It may write beyond the bounds of the destination buffer when attempting to write a padded, thousands-separated string representation of a number, if the buffer is allocated the exact size required to represent that number as a string. For example, 1,234,567 (with padding to 13) overflows by two bytes.
CVE-2023-6780 2 Fedoraproject, Gnu 2 Fedora, Glibc 2025-02-07 N/A 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 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-2023-5156 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-2023-4527 4 Fedoraproject, Gnu, Netapp and 1 more 32 Fedora, Glibc, H300s and 29 more 2024-11-21 N/A 6.5 MEDIUM
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.
CVE-2023-0687 1 Gnu 1 Glibc 2024-11-21 4.0 MEDIUM 4.6 MEDIUM
A vulnerability was found in GNU C Library 2.38. It has been declared as critical. This vulnerability affects the function __monstartup of the file gmon.c of the component Call Graph Monitor. The manipulation leads to buffer overflow. It is recommended to apply a patch to fix this issue. VDB-220246 is the identifier assigned to this vulnerability. NOTE: The real existence of this vulnerability is still doubted at the moment. The inputs that induce this vulnerability are basically addresses of the running application that is built with gmon enabled. It's basically trusted input or input that needs an actual security flaw to be compromised or controlled.
CVE-2022-39046 2 Gnu, Netapp 12 Glibc, H300s, H300s Firmware and 9 more 2024-11-21 N/A 7.5 HIGH
An issue was discovered in the GNU C Library (glibc) 2.36. When the syslog function is passed a crafted input string larger than 1024 bytes, it reads uninitialized memory from the heap and prints it to the target log file, potentially revealing a portion of the contents of the heap.
CVE-2021-43396 2 Gnu, Oracle 7 Glibc, Communications Cloud Native Core Binding Support Function, Communications Cloud Native Core Network Function Cloud Native Environment and 4 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
In iconvdata/iso-2022-jp-3.c in the GNU C Library (aka glibc) 2.34, remote attackers can force iconv() to emit a spurious '\0' character via crafted ISO-2022-JP-3 data that is accompanied by an internal state reset. This may affect data integrity in certain iconv() use cases. NOTE: the vendor states "the bug cannot be invoked through user input and requires iconv to be invoked with a NULL inbuf, which ought to require a separate application bug to do so unintentionally. Hence there's no security impact to the bug.
CVE-2021-3999 3 Debian, Gnu, Netapp 15 Debian Linux, Glibc, E-series Performance Analyzer and 12 more 2024-11-21 N/A 7.8 HIGH
A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system.
CVE-2021-33574 4 Debian, Fedoraproject, Gnu and 1 more 20 Debian Linux, Fedora, Glibc and 17 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact.
CVE-2020-6096 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Glibc 2024-11-21 6.8 MEDIUM 8.1 HIGH
An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc 2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the 'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data.
CVE-2020-29573 3 Gnu, Netapp, Redhat 4 Glibc, Cloud Backup, Solidfire Baseboard Management Controller and 1 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference.
CVE-2020-1752 4 Canonical, Debian, Gnu and 1 more 9 Ubuntu Linux, Debian Linux, Glibc and 6 more 2024-11-21 3.7 LOW 7.0 HIGH
A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32.
CVE-2020-1751 3 Canonical, Gnu, Redhat 3 Ubuntu Linux, Glibc, Enterprise Linux 2024-11-21 5.9 MEDIUM 5.1 MEDIUM
An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the frame address, resulting in a denial of service or potential code execution. The highest threat from this vulnerability is to system availability.
