Alpine: borg: security update to 1.2.4-r5 (deprecated)

medium Tenable Self-Hosted Container Security Plugin ID 401357

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- borgbackup is an opensource, deduplicating archiver with compression and authenticated encryption. A flaw
in the cryptographic authentication scheme in borgbackup allowed an attacker to fake archives and
potentially indirectly cause backup data loss in the repository. The attack requires an attacker to be
able to: 1. insert files (with no additional headers) into backups and 2. gain write access to the
repository. This vulnerability does not disclose plaintext to the attacker, nor does it affect the
authenticity of existing archives. Creating plausible fake archives may be feasible for empty or small
archives, but is unlikely for large archives. The issue has been fixed in borgbackup 1.2.5. Users are
advised to upgrade. Additionally to installing the fixed code, users must follow the upgrade procedure as
documented in the change log. Data loss after being attacked can be avoided by reviewing the archives
(timestamp and contents valid and as expected) after any "borg check --repair" and before "borg prune".
There are no known workarounds for this vulnerability. (CVE-2023-36811)
