po4a is a set of tools for helping with the translation of documentation.
The po4a development team reported a race condition in the gettextize() function when creating the file "/tmp/gettextization.failed.po".
A local attacker could perform a symlink attack, possibly overwriting files with the permissions of the user running po4a.
There is no known workaround at this time.
All po4a users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/po4a-0.32-r1"
