Description

Problem Description An error in the handling of corrupt compressed data streams can result in a buffer being overflowed. Impact By carefully crafting a corrupt compressed data stream, an attacker can overwrite data structures in a zlib-using application. This may cause the application to halt, causing a denial of service; or it may result in the attacker gaining elevated privileges.
