DSA-077-1 squid -- remote DoS

Date Reported:

24 Sep 2001

Affected Packages:

squid

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 3354.
In Mitre's CVE dictionary: CVE-2001-0843.

More information:

Vladimir Ivaschenko found a problem in squid (a popular proxy cache). He discovered that there was a flaw in the code to handle FTP PUT commands: when a mkdir-only request was done squid would detect an internal error and exit. Since squid is configured to restart itself on problems this is not a big problem.

This has been fixed in version 2.2.5-3.2. This problem is logged as bug 233 in the squid bugtracker and will also be fixed in future squid releases.

Fixed in:

Debian GNU/Linux 2.2 (potato)
