[DSA120] DSA-120-1 mod_ssl |

DSA-120-1 mod_ssl Detailed Explanation for this Vulnerability Assessment Ed Moyle recently found a buffer overflow in Apache-SSL and mod_ssl. With session caching enabled, mod_ssl will serialize SSL session variables to store them for later use. These variables were stored in a buffer of a fixed size without proper boundary checks. To exploit the overflow, the server must be configured to require client certificates, and a possible hacker must obtain a carefully crafted client certificate that has been signed by a Certificate Authority which is trusted by the server. If these conditions are met, it would be possible for a possible hacker to execute arbitrary code on the server. This problem has been fixed in version 1.3.9.13-4 of Apache-SSL and version 2.4.10-1.3.9-1potato1 of libapache-mod-ssl for the stable Debian distribution as well as in version 1.3.23.1+1.47-1 of Apache-SSL and version 2.8.7-1 of libapache-mod-ssl for the testing and unstable distribution of Debian. We recommend that you upgrade your Apache-SSL and mod_ssl packages.
