CVE-2015-8932 (opens in a new tab)How to fix?
Upgrade RHEL:7 libarchive to version 0:3.1.2-10.el7_2 or higher.
This issue was patched in RHSA-2016:1844.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libarchive package and not the libarchive package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
The compress_bidder_init function in archive_read_support_filter_compress.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (crash) via a crafted tar file, which triggers an invalid left shift.
