Date: September 09, 2009
Bugs: #245765
ID: 200909-11

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

1 dev-cpp/gccxml < 0.9.0_pre20090516 >= 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
