Name of the Vulnerable Software and Affected Versions nginx versions prior to 1.0.10

Description The issue is related to a heap-based buffer overflow in compression-pointer processing. This occurs in the core/ngx resolver.c file of the nginx software. Remote resolvers can potentially cause a denial of service, leading to a daemon crash, or possibly have other unspecified impacts by sending a long response.

Recommendations For versions prior to 1.0.10, update to version 1.0.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the core/ngx resolver.c module to minimize the risk of exploitation.
