Debian Security Advisory DSA 532-2 security@debian.org
http://www.debian.org/security/ Matt Zimmerman
July 27th, 2004 http://www.debian.org/security/faq
- - --------------------------------------------------------------------------
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.
