These are not vulnerable for now but still not nice to have around.

Comment 1 René Rhéaume (a.k.a. repzilon, rener) 2008-12-24 23:22:46 UTC

Ebuilds for versions 0.4.3 and 0.4.5 had ext-zlib and ext-png USE flags. They are in the Attic of the gentoo-x86 repository.

The bundled libraries are modified versions. Modifications include removing the contrib directory (except for optimized routines in assembly), marking the modified version as such, disable unused parts of zlib in optipng and defining TOO_FAR to 32768 in zlib to slightly increase the compression ratio. There are diff files in the lib/lib_diff directory of the source distribution.

Fixed in 0.6.3, thanks.
