Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-071 advisory.An improper link resolution flaw can occur while extracting an archive leading to changing modes, times, access control lists, and flags of a file outside of the archive. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to gain more privileges in a system. (CVE-2021-31566)
A use-after-free flaw was found in libarchive in the copy_string function. (CVE-2021-36976)
An out-of-bounds read flaw was found in libarchive. This flaw allows an attacker who can supply a specially crafted zip file to libarchive to cause an out-of-bounds read in programs linked with libarchive, using the LZMA zip functionality. The consequences depend on the specific program linked with libarchive. Still, they would most likely result in an application crash or information disclosure that could be used in conjunction with another exploit. (CVE-2022-26280)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Run 'dnf update libarchive --releasever=2023.0.20230222 ' to update your system.See Also
