CVE-2016-4300 (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.
Integer overflow in the read_SubStreamsInfo function in archive_read_support_format_7zip.c in libarchive before 3.2.1 allows remote attackers to execute arbitrary code via a 7zip file with a large number of substreams, which triggers a heap-based buffer overflow.
