An improper link resolution flaw while extracting an archive can lead to changing the access control list (ACL) of the target of the link. 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 change the ACL of a file on the system and gain more privileges.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:0892 advisory.

  - An improper link resolution flaw while extracting an archive can lead to changing the access control list     (ACL) of the target of the link. 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 change the ACL     of a file on the system and gain more privileges. (CVE-2021-23177)

  - 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)
