Name of the Vulnerable Software and Affected Versions
GNU C Library versions 2.34 through 2.43
Description
The GNU C Library contains a flaw where calling the
gethostbyaddr or gethostbyaddr r functions with a specific nsswitch.conf configuration utilizing the library’s DNS backend may lead to a violation of the DNS specification. A crafted response from a configured DNS server could cause the application to incorrectly interpret a non-answer section of the DNS response as a valid answer.Recommendations
Versions prior to 2.34 or after 2.43 should be used.
