Description :

Updated tk packages that fix a security issue are now available for

Tk is a graphical toolkit for the Tcl scripting language.

An input validation flaw was discovered in Tk's GIF image handling. A
code-size value read from a GIF image was not properly validated
before being used, leading to a buffer overflow. A specially crafted
GIF file could use this to cause a crash or, potentially, execute code
with the privileges of the application using the Tk graphical toolkit.
