Package : fetchmail
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-2335
CERT advisory :
BugTraq ID : 14349
Debian Bug : 212762

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.
