Description

SO-AND-SO reports:

A memory corruption issue was found in Artifex

Ghostscript 9.50 and 9.52. Use of a non-standard

PostScript operator can allow overriding of file access

controls. The 'rsearch' calculation for the 'post' size

resulted in a size that was too large, and could underflow

to max uint32_t. This was fixed in commit

5d499272b95a6b890a1397e11d20937de000d31b.
