Summary
The remote host is missing an update to fetchmail announced via advisory DSA 774-1. 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.
