CVE-2020-15900 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ghostscript package and not the ghostscript package as distributed by Debian.
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.
