Gnu Glibc vulnerabilities

CVE-2020-1751 [HIGH] CWE-787 CVE-2020-1751: An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines 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.

CVE-2020-1752 [HIGH] CWE-416 CVE-2020-1752: A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the ti 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, w

CVE-2017-12133 [MEDIUM] CWE-416 CVE-2017-12133: Use-after-free vulnerability in the clntudp_call function in sunrpc/clnt_udp.c in the GNU C Library Use-after-free vulnerability in the clntudp_call function in sunrpc/clnt_udp.c in the GNU C Library (aka glibc or libc6) before 2.26 allows remote attackers to have unspecified impact via vectors related to error path.

CVE-2023-6780 [MEDIUM] CWE-131 CVE-2023-6780: An integer overflow was found in the __vsyslog_internal function of the glibc library. This function 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

CVE-2019-25013 [MEDIUM] CWE-125 CVE-2019-25013: The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid mu The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read.

CVE-2015-1473 [MEDIUM] CWE-119 CVE-2015-1473: The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boun

CVE-2024-33600 [MEDIUM] CWE-476 CVE-2024-33600: nscd: Null pointer crashes after notfound response If the Name Service Cache Daemon's (nscd) cache nscd: Null pointer crashes after notfound response If the Name Service Cache Daemon's (nscd) cache fails to add a not-found netgroup response to the cache, the client request can result in a null pointer dereference. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.

CVE-2016-10228 [MEDIUM] CWE-20 CVE-2016-10228: The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with mult The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, leading to a denial of service.

CVE-2015-5277 [HIGH] CWE-119 CVE-2015-5277: The get_contents function in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library The get_contents function in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) before 2.20 might allow local users to cause a denial of service (heap corruption) or gain privileges via a long line in the NSS files database.

CVE-2013-7423 [MEDIUM] CWE-17 CVE-2013-7423: The send_dg function in resolv/res_send.c in GNU C Library (aka glibc or libc6) before 2.20 does not The send_dg function in resolv/res_send.c in GNU C Library (aka glibc or libc6) before 2.20 does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function.

CVE-2023-4813 [MEDIUM] CWE-416 CVE-2023-4813: A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.

CVE-2023-4806 [MEDIUM] CWE-416 CVE-2023-4806: A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may ac A flaw has been identified 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 r
