Description Josh Bressers 2005-10-21 16:10:33 UTC 
Chris Evans reported several issues with libungif to vendor-sec.  They have been
fixed in libungif-4.1.4, but not noted as security issues.

"I believe that the recently released libungif-4.1.4 fixes these
crashes. Credit here must go to Daniel Eisenbud who independently
noticed libungif crashes _and_ patched it to fix it."

These issue should also affect RHEL2.1 and RHEL3
