  script_tag(name:"insight", value:"New kernels are available for Slackware 9.1 and -current to fix
a bounds-checking problem in the kernel's mremap() call which
could be used by a local attacker to gain root privileges.
Please note that this is not the same issue as CAN-2003-0985
which was fixed in early January.

The kernels in Slackware 8.1 and 9.0 that were updated in
January are not vulnerable to this new issue because the patch
from Solar Designer that was used to fix the CAN-2003-0985 bugs
also happened to fix the problem that was discovered later.

Sites running Slackware 9.1 or -current should upgrade to a
new kernel. After installing the new kernel, be sure to run
'lilo'.

Vulnerabilities and Exposures (CVE) database:

Here are the details from the Slackware 9.1 ChangeLog:
+--------------------------+
Wed Feb 18 03:44:42 PST 2004
patches/kernels/: Recompiled to fix another bounds-checking error in
 the kernel mremap() code. (this is not the same issue that was fixed
 on Jan 6) This bug could be used by a local attacker to gain root
 privileges. Sites should upgrade to a new kernel. After installing
 the new kernel, be sure to run 'lilo'.

 Thanks to Paul Starzetz for finding and researching this issue.
