[slackware-security] openjpeg

New openjpeg packages are available for Slackware 15.0 and -current to
fix a security issue.

Here are the details from the Slackware 15.0 ChangeLog:

patches/packages/openjpeg-2.5.1-i586-1_slack15.0.txz: Upgraded.
Fixed a heap-based buffer overflow in openjpeg in color.c:379:42 in
sycc420_to_rgb when decompressing a crafted .j2k file. An attacker could use
this to execute arbitrary code with the permissions of the application
compiled against openjpeg.

(* Security fix *)
