Dns Glibc Redhat Suse

Description

Calling getnetbyaddr or getnetbyaddr_r with a configured nsswitch.conf that specifies the library's DNS backend for networks and queries for a zero-valued network in the GNU C Library version 2.0 to version 2.42 can leak stack contents to the configured DNS resolver.

Analysis

Stack memory disclosure in GNU C Library versions 2.0-2.42 allows unauthenticated remote attackers to leak sensitive stack contents via crafted DNS queries when getnetbyaddr functions are configured to use the DNS backend for network lookups. This vulnerability affects systems running vulnerable Glibc and DNS resolver combinations, with no available patch currently released.
