The __hash_open function in hash.c:229 in Mozilla Network Security Services (NSS) allows context-dependent attackers to cause a denial of service (floating point exception and crash) via a crafted cert8.db file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
