    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.
