Gentoo Linux Security Advisory
Title: Xlockmore: Denial of Service (GLSA 201309-03)
Severity: normal
Exploitable: local
Date: September 02, 2013
Bug(s): #255229, #440776, #477328
ID: 201309-03
Synopsis
A buffer overflow in Xlockmore might allow remote attackers to
cause a Denial of Service.
Background
Xlockmore is just another screensaver application for X.
Affected Packages
Package: x11-misc/xlockmore
Vulnerable: < 5.43
Unaffected: >= 5.43
Architectures: All supported architectures
Description
A Denial of Service flaw was found in the way Xlockmore performed
the passing of arguments to the underlying localtime() call, when the
‘dlock’ mode was used.
Impact
A local attacker could possibly cause a Denial of Service condition and
potentially obtain unauthorized access to the graphical session,
previously locked by another user.
Workaround
There is no known workaround at this time.
Resolution
All Xlockmore users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=x11-misc/xlockmore-5.43"
|
