CVE-2018-5785

In OpenJPEG 2.3.0, there is an integer overflow caused by an out-of-bounds left shift in the opj_j2k_setup_encoder function (openjp2/j2k.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.

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: 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_next_rlcp, opj_pi_next_rpcl and opj_pi_next_lrcp in openjp2/pi.c (CVE-2020-27845)

• openjpeg: out-of-bounds write due to an integer overflow in opj_compress.c (CVE-2021-29338)
