Gentoo Linux Security Advisory

Title: CUPS: Denial of Service (GLSA 200703-28)
Severity: normal
Exploitable: remote
Date: March 31, 2007
Bug(s): #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: net-print/cups
Vulnerable: < 1.2.9
Unaffected: >= 1.2.9
Architectures: All supported architectures


Description


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-print/cups-1.2.9"


References

CVE-2007-0720
