A buffer overflow in Xlockmore might allow remote attackers to cause a Denial of Service.
| Package | x11-misc/xlockmore on all architectures |
|---|---|
| Affected versions | < 5.43 |
| Unaffected versions | >= 5.43 |
Xlockmore is just another screensaver application for X.
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"
