There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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)

    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)

  - Heap-based Buffer Overflow in GitHub repository strukturag/libde265 prior to and including 1.0.8. The fix
    is established in commit 8e89fe0e175d2870c39486fdd09250b230ec10b8 but does not yet belong to an official
