Description

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

 - A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted
 RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state
 reinitialization. Subsequent processing of another archive entry can trigger a second free of the same
 memory region, resulting in a double-free condition. Successful exploitation may cause applications using
