CVE-2020-27841

There's a flaw in openjpeg in versions prior to 2.4.0 in src/lib/openjp2/pi.c. When an attacker is able to provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The greatest impact from this flaw is to application availability.

OpenJPEG is an open-source JPEG 2000 codec written in C language. It has been developed in order to promote the use of JPEG 2000, a still-image compression standard from the Joint Photographic Experts Group (JPEG). Since April 2015, it is officially recognized by ISO/IEC and ITU-T as a JPEG 2000 Reference Software.

Security Fix(es):

A heap-buffer overflow was found in the way openjpeg2 handled certain PNG format files. An attacker could use this flaw to cause an application crash or in some cases execute arbitrary code with the permission of the user running such an application.(CVE-2020-27814)

Theres a flaw in openjpeg in versions prior to 2.4.0 in src/lib/openjp2/pi.c. When an attacker is able to provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The greatest impact from this flaw is to application availability.(CVE-2020-27841)

A flaw was found in OpenJPEG in versions prior to 2.4.0. This flaw allows an attacker to provide specially crafted input to the conversion or encoding functionality, causing an out-of-bounds read. The highest threat from this vulnerability is system availability.(CVE-2020-27843)

Theres a flaw in src/lib/openjp2/pi.c of openjpeg in versions prior to 2.4.0. If an attacker is able to provide untrusted input to openjpegs conversion/encoding functionality, they could cause an out-of-bounds read. The highest impact of this flaw is to application availability.(CVE-2020-27845)

It was discovered that OpenJPEG incorrectly handled certain image data. An attacker could use this issue to cause OpenJPEG to crash, leading to a denial of service, or possibly execute arbitrary code.

It was discovered that Ghostscript incorrectly handled certain image files. If a user or automated system were tricked into processing a specially crafted file, a remote attacker could use this issue to cause Ghostscript to crash, resulting in a denial of service, or possibly execute arbitrary code.
