DSA-532-2 libapache-mod-ssl -- several vulnerabilities

Date Reported:

27 Jul 2004

Affected Packages:

libapache-mod-ssl

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2004-0488, CVE-2004-0700.

More information:

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.

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.

Fixed in:

Debian GNU/Linux 3.0 (woody)
