libarchive vulnerability
==========================================================================

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

- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

libarchive could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- libarchive: Library to read/write archive files

Details:

It was discovered that libarchive incorrectly handled certain RAR archive
files. If a user or automated system were tricked into processing a
specially crafted RAR archive, an attacker could use this issue to cause
libarchive to crash, resulting in a denial of service, or possibly execute
arbitrary code.

Update instructions:

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

Ubuntu 24.10
   libarchive13t64                 3.7.4-1ubuntu0.1

Ubuntu 24.04 LTS
   libarchive13t64                 3.7.2-2ubuntu0.3

Ubuntu 20.04 LTS
   libarchive13                    3.4.0-2ubuntu1.4

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