|Gentoo Linux Security Advisory
Title: ProFTPD: Format string vulnerabilities (GLSA 200508-02)
Date: August 01, 2005
Under specific circumstances, ProFTPD is vulnerable to format string
vulnerabilities, potentially resulting in the execution of arbitrary code.
ProFTPD is a configurable GPL-licensed FTP server software.
Vulnerable: < 1.2.10-r7
Unaffected: >= 1.2.10-r7
Architectures: All supported architectures
"infamous42md" reported that ProFTPD is vulnerable to format
string vulnerabilities when displaying a shutdown message containing
the name of the current directory, and when displaying response
messages to the client using information retrieved from a database
A remote attacker could create a directory with a malicious name
that would trigger the format string issue if specific variables are
used in the shutdown message, potentially resulting in a Denial of
Service or the execution of arbitrary code with the rights of the user
running the ProFTPD server. An attacker with control over the database
contents could achieve the same result by introducing malicious
messages that would trigger the other format string issue when used in
Do not use the "%C", "%R", or "%U" in shutdown messages, and do
not set the "SQLShowInfo" directive.
All ProFTPD users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.2.10-r7"
