Gentoo: GLSA-200703-28: CUPS: Denial of Service
Summary
Gentoo Linux Security Advisory GLSA 200703-28
https://security.gentoo.org/
Severity: Normal
Title: CUPS: Denial of Service
Date: March 31, 2007
Bugs: #170881
ID: 200703-28
Synopsis
=======
CUPS incorrectly handles partially-negotiated SSL connections allowing
for a Denial of Service.
Background
=========
CUPS provides a portable printing layer for UNIX-based operating
systems.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-print/cups < 1.2.9 >= 1.2.9
==========
CUPS does not properly handle partially-negotiated SSL connections.
Upon receiving a partially-negotiated SSL connection, CUPS no longer
accepts further incoming connections, as the initial connection never
times out.
Impact
=====
An attacker could partially negotiate an SSL connection with a CUPS
server, and cause future connections to that server to fail, resulting
in a Denial of Service.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All CUPS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/cups-1.2.9"
