|---|---|---|---|---|---|---|---|---|
| CVE-2019-9169 | Cri | 0.57 | 9.8 | 0.05 | Feb 26, 2019 | In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-based buffer over-read via an attempted case-insensitive regular-expression match. | ||
| CVE-2021-43396 | Hig | 0.49 | 7.5 | 0.03 | Nov 4, 2021 | 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.… | ||
| CVE-2021-3326 | Hig | 0.42 | 7.5 | 0.04 | Jan 27, 2021 | The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. | ||
| CVE-2018-19591 | Hig | 0.42 | 7.5 | 0.06 | Dec 4, 2018 | In the GNU C Library (aka glibc or libc6) through 2.28, attempting to resolve a crafted hostname via getaddrinfo() leads to the allocation of a socket descriptor that is not closed. This is related to the if_nametoindex() function. | ||
| CVE-2020-27618 | Med | 0.29 | 5.5 | 0.01 | Feb 26, 2021 | The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications,… | ||
| CVE-2019-7309 | Med | 0.29 | 5.5 | 0.01 | Feb 3, 2019 | In the GNU C Library (aka glibc or libc6) through 2.29, the memcmp function for the x32 architecture can incorrectly return zero (indicating that the inputs are equal) because the RDX most significant bit is mishandled. | ||
| CVE-2026-89092 | Med | 0.27 | 4.2 | 0.00 | Sep 11, 2026 | The nscd service in the GNU C Library 2.3.4 onwards may crash due to a stack overflow when a malicious DNS server returns too large a response for a DNS query, resulting in degraded DNS resolution for the system. Exploitation of this bug needs a system that has nscd enabled… | ||
| CVE-2016-10739 | Med | 0.27 | 5.3 | 0.00 | Jan 21, 2019 | In the GNU C Library (aka glibc or libc6) through 2.28, the getaddrinfo function would successfully parse a string that contained an IPv4 address followed by whitespace and arbitrary characters, which could lead applications to incorrectly assume that it had parsed a valid… | ||
| CVE-2020-29562 | Med | 0.24 | 4.8 | 0.02 | Dec 4, 2020 | The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. |
