| CVE-2026-6238 | Med | 6.5 | < 0 | 0 | Apr 28, 2026 | The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to validate the RDATA content against the RDATA length in a DNS response when processing LOC, CERT, TKEY or TSIG records, which may allow an attacker to craft a DNS resp | |

This flaw was introduced in glibc 2.15 | |
| CVE-2024-2961 | Hig | 7.3 | < 2.39-r2 | 2.39-r2 | Apr 17, 2024 | The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. | |
| CVE-2023-6780 | Med | 5.3 | < 2.38-r11 | 2.38-r11 | Jan 31, 2024 | 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 t | |
