Description Lubomir Kundrak 2007-04-16 12:20:13 EDT
Description of problem:

lha doesn't open temporary files exclusively, which makes it possible for an
attacker to conduct a time-dependent attack by creating the file in advance.

Version-Release number of selected component (if applicable):

        Affects: RHEL2.1
        Affects: RHEL3
        Affects: RHEL4
        Affects: FC5

How reproducible:

Time-dependent race.

Additional info:

The patch also incorporates some trailing-NUL things from SUSE's
security review patch. I do not know why weren't they unlike some other
fixes from that patch integrated in our packages. It might be possible
that they are not needed. The patch is basically a polished diff between
SUSE and FC-5 lha.
