Synopsis ========
An insecure temporary file usage has been reported in GCC-XML allowing for symlink attacks.
Background ==========
GCC-XML is an XML output extension to the C++ front-end of GCC.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-cpp/gccxml < 0.9.0_pre20090516 >=3D 0.9.0_pre20090516
Description ===========
Dmitry E. Oboukhov reported that find_flags in GCC-XML does not handle "/tmp/*.cxx" temporary files securely.
Impact ======
A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All GCC-XML users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose =3Ddev-cpp/gccxml-0.9.0_pre20090516
