Amazon Linux 2023 Security Advisory: ALAS-2023-053
Advisory Release Date: 2023-02-17 20:45 Pacific
Advisory Updated Date: 2023-02-22 23:37 Pacific
Severity:
Medium
Issue Overview:
A NULL pointer dereference vulnerability was found in Ghostscript, which occurs when it tries to render a large number of bits in memory. When allocating a buffer device, it relies on an init_device_procs defined for the device that uses it as a prototype that depends upon the number of bits per pixel. For bpp > 64, mem_x_device is used and does not have an init_device_procs defined. This flaw allows an attacker to parse a large number of bits (more than 64 bits per pixel), which triggers a NULL pointer dereference flaw, causing an application to crash. (CVE-2022-2085)
