Date Reported:

12 Aug 2005

Affected Packages:

fetchmail

Vulnerable:

Yes

Security database references:

More information:

Edward Shornock discovered a bug in the UIDL handling code of fetchmail, a common POP3, APOP and IMAP mail fetching utility. A malicious POP3 server could exploit this problem and inject arbitrary code that will be executed on the victim host. If fetchmail is running as root, this becomes a root exploit.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in version 6.2.5-12sarge1.

For the unstable distribution (sid) this problem has been fixed in version 6.2.5-16.

We recommend that you upgrade your fetchmail package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
