[ASA-202012-21] openjpeg2: multiple issues
Arch Linux Security Advisory ASA-202012-21 ========================================== Severity: Medium Date : 2020-12-09 CVE-ID : CVE-2019-12973 CVE-2020-6851 CVE-2020-8112 CVE-2020-15389 CVE-2020-27814 CVE-2020-27824 CVE-2020-27841 CVE-2020-27842 CVE-2020-27843 CVE-2020-27845 Package : openjpeg2 Type : multiple issues Remote : No Link : https://security.archlinux.org/AVG-1339 Summary ======= The package openjpeg2 before version 2.4.0-1 is vulnerable to multiple issues including arbitrary code execution and denial of service. Resolution ========== Upgrade to 2.4.0-1. # pacman -Syu "openjpeg2>=2.4.0-1" The problems have been fixed upstream in version 2.4.0. Workaround ========== None. Description =========== - CVE-2019-12973 (denial of service) In OpenJPEG before version 2.4.0, there is excessive iteration in the opj_t1_encode_cblks function of openjp2/t1.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file. This issue is similar to CVE-2018-6616. - CVE-2020-6851 (arbitrary code execution) OpenJPEG before version 2.4.0 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-2020-8112 (arbitrary code execution) opj_t1_clbl_decode_processor in openjp2/t1.c in OpenJPEG before version 2.4.0 has a heap-based buffer overflow in the qmfbid==1 case, a different issue than CVE-2020-6851. - CVE-2020-15389 (denial of service) jp2/opj_decompress.c in OpenJPEG before version 2.4.0 has a use-after- free that can be triggered if there is a mix of valid and invalid files in a directory operated on by the decompressor. Triggering a double- free may also be possible. This is related to calling opj_image_destroy twice. - CVE-2020-27814 (arbitrary code execution) A heap-buffer overwrite error was discovered in lib/openjp2/mqc.c in OpenJPEG before version 2.4.0. The vulnerability causes an out-of- bounds write, which may lead to remote denial of service or possibly remote code execution. - CVE-2020-27824 (denial of service) In OpenJPEG before version 2.4.0, if too many decomposition levels are supplied to the encoder, it could cause a global buffer overflow to out-of-bounds read in the opj_dwt_calc_explicit_stepsizes() function. - CVE-2020-27841 (denial of service) An out-of-bounds read was discovered in lib/openjp2/pi.c:623 in OpenJPEG before version 2.4.0. - CVE-2020-27842 (denial of service) A null pointer dereference issue was found in lib/openjp2/tgt.c when a small precincts size, the option "-TP C" and non (0,0) grid offset are given in OpenJPEG before version 2.4.0. - CVE-2020-27843 (denial of service) An out-of-bounds read was found in opj_t2_encode_packet when small precincts and an origin shift are given in OpenJPEG before version 2.4.0. - CVE-2020-27845 (denial of service) An out-of-bounds read was discovered in lib/openjp2/pi.c:312 in OpenJPEG before version 2.4.0. Impact ====== A local attacker might be able to execute arbitrary code or crash the application via crafted JPEG content.
