CVE-2016-3142
HighSummary
The phar_parse_zipfile function in the PHAR extension in PHP before versions 5.5.33 and 5.6.19 allows remote attackers to read sensitive information from process memory or cause a denial of service (DoS) via an out-of-bounds read and application crash when a PK\x05\x06 signature is placed at an invalid location.
Risk Assessment
An attacker can access confidential data stored in server memory or cause application downtime, leading to information disclosure and service disruption.
Recommendation
Immediately upgrade PHP to version 5.5.33, 5.6.19, or later to eliminate the out-of-bounds read vulnerability in the phar_parse_zipfile function.
