Artifex: >> Ghostscript >> 9.55.0 Security Vulnerabilities
In Artifex Ghostscript through 10.01.2, gdevijs.c in GhostPDL can lead to remote code execution via crafted PostScript documents because they can switch to the IJS device, or change the IjsServer parameter, after SAFER has been activated. NOTE: it is a documented risk that the IJS server can be specified on a gs command line (the IJS device inherently must execute a command to start the IJS server).

A buffer overflow flaw was found in base/gdevdevn.c:1973 in devn_pcx_write_rle() in ghostscript. This issue may allow a local attacker to cause a denial of service via outputting a crafted PDF file for a DEVN device with gs.

In Artifex Ghostscript through 10.01.0, there is a buffer overflow leading to potential corruption of data internal to the PostScript interpreter, in base/sbcp.c. This affects BCPEncode, BCPDecode, TBCPEncode, and TBCPDecode. If the write buffer is filled to one byte less than full, and one then tries to write an escaped character, two bytes are written.

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.
