Problem Description:
If the end of an archive is reached while attempting to
"skip" past a region of an archive, libarchive will enter an
infinite loop wherein it repeatedly attempts (and fails) to
read further data.
Impact:
An attacker able to cause a system to extract (via "tar -x"
or another application which uses libarchive) or list the
contents (via "tar -t" or another libarchive-using
application) of an archive provided by the attacker can cause
libarchive to enter an infinite loop and use all available
CPU time.
Workaround:
No workaround is available.
