Summary

Multiple libarchive vulnerabilities affect Watson Explorer.

Vulnerability Details

CVEID: CVE-2017-14166 DESCRIPTION: libarchive is vulnerable to a denial of service, caused by a xml_data heap-based buffer over-read issue in the atol8 function in archive_read_support_format_xar.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/131555&gt; for the current score
CVSS Environmental Score*: Undefined
