Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3240 advisory.

- libde265 v1.0.4 contains a heap buffer overflow in the de265_image::available_zscan function, which can be exploited via a crafted a file. (CVE-2020-21599)

- An Incorrect Access Control vulnerability exists in libde265 v1.0.8 due to a SEGV in slice.cc.
(CVE-2021-35452)

- An issue was discovered in libde265 v1.0.8.There is a Heap-use-after-free in intrapred.h when decoding file using dec265. (CVE-2021-36408)

- There is an Assertion `scaling_list_pred_matrix_id_delta==1' failed at sps.cc:925 in libde265 v1.0.8 when decoding file, which allows attackers to cause a Denial of Service (DoS) by running the application with a crafted file or possibly have unspecified other impact. (CVE-2021-36409)

- A stack-buffer-overflow exists in libde265 v1.0.8 via fallback-motion.cc in function put_epel_hv_fallback when running program dec265. (CVE-2021-36410)

- An issue has been found in libde265 v1.0.8 due to incorrect access control. A SEGV caused by a READ memory access in function derive_boundaryStrength of deblock.cc has occurred. The vulnerability causes a segmentation fault and application crash, which leads to remote denial of service. (CVE-2021-36411)

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

Solution

Upgrade the libde265 packages.

For Debian 10 buster, these problems have been fixed in version 1.0.3-1+deb10u1.
