CVE-2014-2497: Null Pointer Dereference

First published: Fri Mar 14 2014(Updated: )

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. <a href="https://access.redhat.com/security/cve/CVE-2014-2497">CVE-2014-2497</a> was assigned to this issue [2].
