Gentoo Linux Security Advisory

Title: GCC-XML: Insecure temporary file usage (GLSA 200909-11)
Severity: normal
Exploitable: local
Date: September 09, 2009
Bug(s): #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

Package: dev-cpp/gccxml
Vulnerable: < 0.9.0_pre20090516
Unaffected: >= 0.9.0_pre20090516
Architectures: All supported architectures


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-cpp/gccxml-0.9.0_pre20090516"


References
