Astra Linux – vulnerability in Redis

Redis is an open-source, in-memory database that persists data on disk. An authenticated user with sufficient privileges can create a malformed ACL selector; upon access, this triggers a server panic followed by a denial of service. The issue affects Redis versions prior to 7.2.6 and 7.4.1. Users...

Astra Linux – vulnerability in libarchive

An improper link resolution flaw during archive extraction can result in changes to the access control list ACL of the target of the link. An attacker can supply a malicious archive to a victim user, causing the flaw to be triggered when that user attempts to extract the archive. A local attacker...
