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.

Affected products

Apache-Ssl: 1.40, 1.41, 1.42, 1.44, 1.45, 1.46
Mod Ssl: 2.7.1, 2.8, 2.8.1, 2.8.2, 2.8.3, 2.8.4 (+2)
