|Gentoo Linux Security Advisory
Title: Xlockmore: Denial of Service (GLSA 201309-03)
Date: September 02, 2013
Bug(s): #255229, #440776, #477328
A buffer overflow in Xlockmore might allow remote attackers to
cause a Denial of Service.
Xlockmore is just another screensaver application for X.
Vulnerable: < 5.43
Unaffected: >= 5.43
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All Xlockmore users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-misc/xlockmore-5.43"
