Vulnerabilities of the `ns_printrrf`, `ns_printrr`, and `fp_nquery` functions in the GNU C Library, allowing attackers to execute arbitrary code

The vulnerability of the nsprintrrf, nsprintrr, and fpnquery functions in the GNU C Library lies in their reliance on buffer overflow attacks. Exploiting this vulnerability could allow a remote attacker to execute arbitrary code...

CVE-2026-6238

The deprecated functions nsprintrrf, nsprintrr and fpnquery in the GNU C Library version 2.0.1 to version 2.43 fail to validate the RDATA content against the RDATA length in a DNS response when processing A6, CERT, LOC, TKEY or TSIG records, which may allow an attacker to craft a DNS response,...

CVE-2026-5435

The deprecated functions nsprintrrf, nsprintrr and fpnquery in the GNU C Library version 2.2 and newer fail to enforce the caller-supplied buffer length, and can result in an out-of-bounds write when printing TSIG records...
