Summary

Qt before 3.3.4 searches the BUILD_PREFIX directory, which could be world-writable, to load shared libraries regardless of the LD_LIBRARY_PATH environment variable, which allows local users to execute arbitrary programs.

descriptionThe remote host is affected by the vulnerability described in GLSA-200503-01 (Qt: Untrusted library search path) Tavis Ormandy of the Gentoo Linux Security Audit Team has discovered that Qt searches for shared libraries in an untrusted, world-writable directory. Impact : A local attacker could create a malicious shared object that would be loaded by Qt, resulting in the execution of arbitrary code with the privileges of the Qt application. Workaround : There is no known workaround at this time.
