Description
Updated openjpeg2 packages fix security vulnerabilities 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).
