Debian Security Advisory DSA 795-2 [email protected]
http://www.debian.org/security/ Michael Stone
September 2, 2005 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
Package : proftpd
Vulnerability : potential code execution
Problem-Type : format string error
Debian-specific: no
CVE ID : CAN-2005-2390
infamous42md reported that proftpd suffers from two format string
vulnerabilities. In the first, a user with the ability to create a
directory could trigger the format string error if there is a
proftpd shutdown message configured to use the "%C", "%R", or "%U"
variables. In the second, the error is triggered if mod_sql is used
to retrieve messages from a database and if format strings have been
inserted into the database by a user with permission to do so.
There was a build error for the sarge i386 proftpd packages released
in DSA 795-1. A new build, 1.2.10-15sarge1.0.1, has been prepared to
correct this error. The packages for other architectures are
unaffected.
