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_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)
