A vulnerability in CUPS allows remote attackers to cause a denial of service when sending a carefully-crafted UDP packet to the IPP port.
|Package||net-print/cups on all architectures|
|Affected versions||< 1.1.20-r2|
|Unaffected versions||>= 1.1.20-r2|
The Common UNIX Printing System (CUPS) is a cross-platform print spooler.
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"
