Name of the Vulnerable Software and Affected Versions LTTng Userspace Tracer (aka UST) version 0.7

Description The issue allows local users to gain privileges via a Trojan horse shared library in the current working directory. This is due to usttrace in LTTng Userspace Tracer placing a zero-length directory name in the LD LIBRARY PATH.

Recommendations For version 0.7, consider restricting access to the LD LIBRARY PATH environment variable to prevent malicious library loading until a patch is available. As a temporary workaround, avoid using the current working directory for library loading to minimize the risk of exploitation.
