Summary: openjpeg2 security update

Details: 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 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.(CVE-2020-27824) opj_t1_clbl_decode_processor in openjp2/t1.c in OpenJPEG 2.3.1 through 2020-01-28 has a heap-based buffer overflow in the qmfbid==1 case, a different issue than CVE-2020-6851.(CVE-2020-8112) AOpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t1.c because of lack of opj_j2k_update_image_dimensions validation.(CVE-2020-6851)
