The remote host is affected by the vulnerability described in GLSA-202208-26 (libarchive: Multiple Vulnerabilities)
libarchive 3.4.1 through 3.5.1 has a use-after-free in copy_string (called from do_uncompress_block and process_block). (CVE-2021-36976)
Libarchive v3.6.0 was discovered to contain an out-of-bounds read via the component zipx_lzma_alone_init.
(CVE-2022-26280)
REJECT DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2022-26280. Reason: This candidate is a duplicate of CVE-2022-26280. Notes: All CVE users should reference CVE-2022-26280 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage. (CVE-2022-28066)
libarchive: symbolic links incorrectly followed when changing modes, times, ACL and flags of a file while extracting an archive (CVE-2021-31566)
Note that Nessus has not tested for these issues but has instead relied only on the applicationβs self-reported version number.
