Gnome Gnumeric 'ms_escher_get_data()' Function Heap Based Buffer Overflow Vulnerability

Gnumeric is prone to a remote heap-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.

Successful exploits allow remote attackers to execute arbitrary code in the context of the vulnerable application. Failed exploit attempts will likely result in denial-of-service conditions.

Gnumeric prior to 1.12.9 are vulnerable.
