Description Agostino Sarubbo gentoo-dev 2014-03-17 09:56:47 UTC 
From ${URL} :

It was reported [1] that the gdImageCreateFromXpm() function in libgd could dereference a NULL pointer, 
noting:

"The call to strlen() parses image.colorTable[i].c_color which is initialised as NULL if the particular 
color mapping uses a different key (such as monochrome/monovisual)."

This was reported against PHP, which includes an embedded copy of the gd library.  CVE-2014-2497 was 
assigned to this issue [2].

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
