CVE-2002-0082 Information

Description

The dbm and shm session cache code in mod_ssl before 2.8.7-1.3.23 and Apache-SSL before 1.3.22+1.46 does not properly initialize memory using the i2d_SSL_SESSION function which allows remote attackers to use a buffer overflow to execute arbitrary code via a large client certificate that is signed by a trusted Certificate Authority (CA) which produces a large serialized session.
