==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in RAR.

Software Description:
- rar: Archiver for .rar files

Details:

It was discovered that RAR incorrectly handled certain paths. If a user or
automated system were tricked into extracting a specially crafted RAR
archive, a remote attacker could possibly use this issue to write arbitrary
files outside of the targeted directory. (CVE-2022-30333)

It was discovered that RAR incorrectly handled certain recovery volumes. If
a user or automated system were tricked into extracting a specially crafted
RAR archive, a remote attacker could possibly use this issue to execute
arbitrary code. (CVE-2023-40477)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS
   rar                             2:6.23-1~22.04.1

Ubuntu 20.04 LTS
   rar                             2:6.23-1~20.04.1

fixes. In general, a standard system update will make all the necessary
changes.
