Multiple vulnerabilities have been discovered in openjpeg2, the open-source JPEG 2000 codec.

CVE-2018-6616

Excessive iteration in the opj_t1_encode_cblks function (openjp2/t1.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.

CVE-2018-14423

Division-by-zero vulnerabilities in the functions pi_next_pcrl, pi_next_cprl, and pi_next_rpcl in (lib/openjp3d/pi.c). Remote attackers could leverage this vulnerability to cause a denial of service (application crash).

For Debian 8 'Jessie', these problems have been fixed in version 2.1.0-2+deb8u6.

We recommend that you upgrade your openjpeg2 packages.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1252-1 advisory.

  - Division-by-zero vulnerabilities in the functions pi_next_pcrl, pi_next_cprl, and pi_next_rpcl in     lib/openjp3d/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service     (application crash). (CVE-2018-14423)

  - An issue was discovered in OpenJPEG 2.3.0. Missing checks for header_info.height and header_info.width in     the function pnmtoimage in bin/jpwl/convert.c can lead to a heap-based buffer overflow. (CVE-2018-16375)

  - An issue was discovered in OpenJPEG 2.3.0. A heap-based buffer overflow was discovered in the function     t2_encode_packet in lib/openmj2/t2.c. The vulnerability causes an out-of-bounds write, which may lead to     remote denial of service or possibly unspecified other impact. (CVE-2018-16376)

  - Division-by-zero vulnerabilities in the functions pi_next_pcrl, pi_next_cprl, and pi_next_rpcl in     openmj2/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service (application     crash). (CVE-2018-20845)

  - In OpenJPEG 2.3.0, there is an integer overflow vulnerability in the opj_t1_encode_cblks function     (openjp2/t1.c). Remote attackers could leverage this vulnerability to cause a denial of service via a     crafted bmp file. (CVE-2018-5727)

  - 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. (CVE-2018-5785)

  - In OpenJPEG 2.3.0, 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.
    (CVE-2018-6616)

  - jp2/opj_decompress.c in OpenJPEG through 2.3.1 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-2020-15389)

  - 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)

  - OpenJPEG 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)

  - 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)

  - Integer Overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of     Service (DoS). This occurs when the attacker uses the command line option -ImgDir on a directory that     contains 1048576 files. (CVE-2021-29338)

  - A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input     directory with a large number of files. When it fails to allocate a buffer to store the filenames of the     input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial     of service. (CVE-2022-1122)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
