ghostscript: A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52
CVE-2020-15900 is fixed in 4 products on 1 platform, first by ghostscript 9.50~dfsg-5ubuntu4.1, released July 28, 2020. It is not reported as exploited. Patch Radar priority: Routine.
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.
