ALSA-2021:4251 — Moderate: openjpeg2 security update

Affected: AlmaLinux:8: openjpeg2, AlmaLinux:8: openjpeg2-devel, AlmaLinux:8: openjpeg2-devel-docs, AlmaLinux:8: openjpeg2-tools

OpenJPEG is an open source library for reading and writing image files in JPEG2000 format.

The following packages have been upgraded to a later upstream version: openjpeg2 (2.4.0).

Security Fix(es):

* openjpeg: use-after-free and double-free via a mix of valid and invalid files in a directory operated on by the decompressor (CVE-2020-15389)

* openjpeg: heap-buffer-overflow in lib/openjp2/mqc.c could result in DoS (CVE-2020-27814)

* openjpeg: heap-buffer-overflow write in opj_tcd_dc_level_shift_encode() (CVE-2020-27823)

* openjpeg: heap-buffer-overflow in color.c may lead to DoS or arbitrary code execution (CVE-2021-3575)

* openjpeg: integer overflow in opj_t1_encode_cblks in src/lib/openjp2/t1.c (CVE-2018-5727)

* openjpeg: integer overflow in opj_j2k_setup_encoder function in openjp2/j2k.c (CVE-2018-5785)

* openjpeg: division-by-zero in functions pi_next_pcrl, pi_next_cprl, and pi_next_rpcl in openmj2/pi.c (CVE-2018-20845)

* openjpeg: integer overflow in function opj_get_encoding_parameters in openjp2/pi.c (CVE-2018-20847)

* openjpeg: denial of service in function opj_t1_encode_cblks in openjp2/t1.c (CVE-2019-12973)

* openjpeg: global-buffer-overflow read in opj_dwt_calc_explicit_stepsizes() (CVE-2020-27824)

* openjpeg: null pointer dereference in opj_tgt_reset function in lib/openjp2/tgt.c (CVE-2020-27842)

* openjpeg: out-of-bounds read in opj_t2_encode_packet function in openjp2/t2.c (CVE-2020-27843)

* openjpeg: heap-based buffer overflow in functions opj_pi…

There's 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 openjpeg's conversion/encoding functionality, they could cause an out-of-bounds read. The highest impact of this flaw is to application availability.

OESA-2021-1118 — openjpeg2 security update

Affected: openEuler:20.03-LTS: openjpeg2, openEuler:20.03-LTS-SP1: openjpeg2

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)
