 Mandriva Linux Security Advisory                         MDVSA-2011:155
 http://www.mandriva.com/security/
 _______________________________________________________________________

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

 Problem Description:

 Multiple vulnerabilities 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).
 
 SystemTap 1.4, 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 stack unwinding
 (aka backtracing) (CVE-2011-1781).
 
 The updated packages have been patched to correct these issues.
