Detail

Several vulnerabilities were discovered in SystemTap, an instrumentation system for Linux:

CVE-2011-2503

It was discovered that a race condition in staprun could lead to privilege escalation.

CVE-2010-4170

It was discovered that insufficient validation of environment variables in staprun could lead to privilege escalation.

CVE-2010-4171

It was discovered that insufficient validation of module unloading could lead to denial of service.

For the stable distribution (squeeze), this problem has been fixed in version 1.2-5+squeeze1.

For the unstable distribution (sid), this problem has been fixed in version 1.6-1.

We recommend that you upgrade your systemtap packages.

Id Description
74148 SystemTap staprun Race Condition Module Loading Local Privilege Escalation

69490 SystemTap /usr/bin/staprun Arbitrary Unused Module Unloading Local DoS

SystemTap contains a flaw that may allow a local denial of service. The issue is triggered when a flaw in '/usr/bin/staprun' when unloading kernel modules is exploited to unload unused modules, which will result in loss of availability.
69489 SystemTap /usr/bin/staprun Kernel Module Loading Local Privilege Escalation

SystemTap contains a flaw that may allow an attacker to gain access to unauthorized privileges. The issue is triggered when /usr/bin/staprun fails to properly sanitize the environment before loading an additional kernel module. This allows a local attacker to escalate their privileges.
