Originalnachricht |
A root exploit has been found in xlockmore packaged with Slackware. By providing a carefully crafted display variable to xlock, it is possible for a local attacker to gain root access. Anyone running xlock on a public machine should upgrade to this version of xlock (or disable xlock altogether) immediately.
The package described below will work for users of Slackware 7.0, 7.1, and -current.
=========================================== xlockmore 4.17.2 AVAILABLE - (x1/xlock.tgz) ===========================================
A root exploit has been fixed in this release of xlockmore. The new xlock.tgz package is available from:
xlock.tgz
For verification purposes, we provide the following checksums:
16-bit "sum" checksum: 53857 762 x1/xlock.tgz
128-bit MD5 message digest: ca171919342cd7a3e18a3ac3cd91e252 x1/xlock.tgz
INSTALLATION INSTRUCTIONS FOR THE xlock.tgz PACKAGE: --------------------------------------------------- Disable any running xlockmore processes and issue this command:
# upgradepkg xlock.tgz
Remember, it's also a good idea to backup configuration files before upgrading packages.
