Description
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.
Affected configurations
• artifex ghostscript 9.50
• artifex ghostscript 9.52
• canonical ubuntu linux 20.04
• opensuse leap 15.1
• opensuse leap 15.2
