Ghostscript: ghostscript: -dsafer sandbox bypass via type 5 shading oob write and procedure-stream use-after-free

A flaw was found in Ghostscript. When Ghostscript renders a crafted PostScript or EPS document, it can bypass the -dSAFER sandbox and execute arbitrary shell commands in the context of the Ghostscript process. The issue chains memory corruption in document parsing with disabling of internal path access controls at runtime. An attacker can deliver the document directly or through formats that delegate rendering to Ghostscript (for example EPS import or print conversion workflows). Successful exploitation can compromise confidentiality, integrity, and availability of data accessible to the process running Ghostscript.

Artifex Ghostscript Pdfwrite gdevpsfx.c type1_callsubr stack-based overflow

A vulnerability was identified in Artifex Ghostscript up to 10.07.0. Affected is the function type1_callsubr of the file devices/vector/gdevpsfx.c of the component Pdfwrite. The manipulation leads to stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. Upgrading to version 10.08.0 is able to address this issue. It is suggested to upgrade the affected component. A solution was implemented: "I've chosen to fix this slightly differently by using the defined macro in the font parsing loop rather than in the callsubr function, because this better matches the pattern of 'no

Ghostscript < 10.08.0 Heap Buffer Overflow via JPEG 2000 Output Adapter

Ghostscript before 10.08.0 contains a heap-based buffer overflow vulnerability in the JPEG 2000 output adapter (base/sjpx_openjpeg.c) that allows attackers to cause memory corruption by supplying a crafted PDF containing a JPEG 2000 image with mismatched component subsampling factors. When image components declare different subsampling values, the non-samescale sub-byte-depth output path allocates a row buffer sized for packed output but writes a full byte per output column regardless of bit depth, overflowing the allocation and corrupting internal chunk-allocator metadata to achieve code execution.

uclouvain openjpeg pi.c opj_pi_initialise_encode integer overflow

A vulnerability was identified in uclouvain openjpeg up to 2.5.4. This impacts the function opj_pi_initialise_encode in the library src/lib/openjp2/pi.c. The manipulation leads to integer overflow. The attack must be carried out locally. The exploit is publicly available and might be used. The identifier of the patch is 839936aa33eb8899bbbd80fda02796bb65068951. It is suggested to install a patch to address this issue.
