CVE-2026-5435

Name of the Vulnerable Software and Affected Versions glibc versions 2.2 and newer

Description The deprecated functions ns printrrf(), ns printrr(), and fp nquery() fail to enforce the caller-supplied buffer length. This can lead to an out-of-bounds write, which occurs when data is written outside the boundaries of a pre-allocated fixed-length block of memory, specifically when printing TSIG records.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
