Debian Security Advisory DSA 532-2 security@debian.org

Package : libapache-mod-ssl
Vulnerability : several
Problem-Type : remote
Debian-specific: no
CVE Ids : CAN-2004-0488 CAN-2004-0700

Two vulnerabilities were discovered in libapache-mod-ssl:

CAN-2004-0488 – Stack-based buffer overflow in the
ssl_util_uuencode_binary function in ssl_util.c for Apache mod_ssl,
when mod_ssl is configured to trust the issuing CA, may allow
remote attackers to execute arbitrary code via a client certificate
with a long subject DN.

CAN-2004-0700 – Format string vulnerability in the ssl_log
function in ssl_engine_log.c in mod_ssl 2.8.19 for Apache 1.3.31
may allow remote attackers to execute arbitrary messages via format
string specifiers in certain log messages for HTTPS.

This is a revision to DSA 531-1, due to a problem with a
documentation symlink in the previous version of the i386 binary
package.

For the current stable distribution (woody), these problems have
been fixed in version 2.8.9-2.4.

For the unstable distribution (sid), CAN-2004-0488 was fixed in
version 2.8.18, and CAN-2004-0700 will be fixed soon.

We recommend that you update your libapache-mod-ssl package.
