Kerentanan Integer Underflow (Wrap or Wraparound) pada artifex ghostscript, canonical ubuntu linux +1 lainnya. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

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.
