A vulnerability was identified in JasPer up to 4.2.5. This affects the function jpc_dec_dump of the file src/libjasper/jpc/jpc_dec.c of the component JPEG2000 File Handler. The manipulation leads to use after free. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The patch is named 8308060d3fbc1da10353ac8a95c8ea60eba9c25a. It is recommended to apply a patch to fix this issue.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:3947-1 advisory.

    - Update to 4.2.8:

    - CVE-2025-8837: Fixed a bug in the JPC decoder that could cause bad memory accesses if the debug level is     set sufficiently high (bsc#1247901).
    - CVE-2025-8836: Added some missing range checking on several coding parameters in the JPC encoder     (bsc#1247902).
    - CVE-2025-8835: Added a check for a missing color component in the jas_image_chclrspc function     (bsc#1247904).
    - CVE-2023-51257: Fixed invalid memory write bug (bsc#1218802).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:03367-1 advisory.

    - CVE-2025-8835: missing range check in the JPEG-2000 (JPC) Encoder leads to assertion failure and crash     when       processing a malformed JPEG2000 image with an invalid `cblkwidth` parameter (bsc#1247904).
    - CVE-2025-8836: out-of-bounds array indexing in function `jas_image_chclrspc` leads to crash when     processing a       malformed image file with BMP output format and color space conversion (bsc#1247902).
    - CVE-2025-8837: missing operations in cleanup code of the JPEG-2000 (JPC) Encoder leads to use-after-free     when       processing malformed JPEG2000 images with certain debug levels enabled (bsc#1247901).
