 Mandriva Linux Security Advisory                         MDVSA-2011:154
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : systemtap
 Date    : October 17, 2011
 Affected: 2010.1
 _______________________________________________________________________

 Problem Description:

 A vulnerability has been discovered and corrected in systemtap:
 
 SystemTap 1.4 and earlier, when unprivileged (aka stapusr)
 mode is enabled, allows local users to cause a denial of service
 (divide-by-zero error and OOPS) via a crafted ELF program with DWARF
 expressions that are not properly handled by a stap script that
 performs context variable access (CVE-2011-1769).
 
 The updated packages have been patched to correct this issue.
