Title: CUPS: Denial of service vulnerability (GLSA 200409-25)
Date: September 20, 2004
Updated: September 21, 2004
A vulnerability in CUPS allows remote attackers to cause a denial of service when sending a carefully-crafted UDP packet to the IPP port.
The Common UNIX Printing System (CUPS) is a cross-platform print spooler.
Vulnerable: < 1.1.20-r2
Unaffected: >= 1.1.20-r2
Architectures: All supported architectures
Alvaro Martinez Echevarria discovered a hole in the CUPS Internet Printing Protocol (IPP) implementation that allows remote attackers to cause CUPS to stop listening on the IPP port.
A remote user with malicious intent can easily cause a denial of service to the CUPS daemon by sending a specially-crafted UDP datagram packet to the IPP port.
There is no known workaround at this time.
All CUPS users should upgrade to the latest version:
|# emerge sync
# emerge -pv ">=net-print/cups-1.1.20-r2"
# emerge ">=net-print/cups-1.1.20-r2"
