CVE-2020-27824

A flaw was found in OpenJPEG’s encoder in the opj_dwt_calc_explicit_stepsizes() function. This flaw allows an attacker who can supply crafted input to decomposition levels to cause a buffer overflow. The highest threat from this vulnerability is to system 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 flaw was found in OpenJPEG’s encoder. This flaw allows an attacker to pass specially crafted x,y offset input to OpenJPEG to use during encoding. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.(CVE-2020-27823)

A heap-buffer overwrites error was discovered in lib/openjp2/mqc.c in OpenJPEG 2.3.1. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly remote code execution (CVE-2020-27814).

A flaw was found in OpenJPEG’s encoder. This flaw allows an attacker to pass specially crafted x,y offset input to OpenJPEG to use during encoding. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability (CVE-2020-27823).

There is a flaw in openjpeg's encoder in the opj_dwt_calc_explicit_stepsizes() function. An attacker who is able to supply crafted input to decomposition levels could cause a buffer overflow, potentially causing an impact to application availability (CVE-2020-27824).
