+ <title>f2c: Insecure temporary file creation</title>
+ <synopsis>
+ f2c is vulnerable to symlink attacks, potentially allowing a local user to
+ overwrite arbitrary files.

+ <background>
+ <p>
+ f2c is a Fortran to C translator. Portage uses this package in
+ some ebuilds to build Fortran sources.

+ <description>
+ <p>
+ Javier Fernandez-Sanguino Pena from the Debian Security Audit Team
+ discovered that f2c creates temporary files in world-writeable
+ directories with predictable names.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ A local attacker could create symbolic links in the temporary
+ files directory, pointing to a valid file somewhere on the filesystem.
+ When f2c is executed, this would result in the file being overwritten
+ with the rights of the user running the software, which could be the
+ root user.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All f2c users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/f2c-20030320-r1&quot;</code>
