Description

This security bulletin contains information about 1 security vulnerability.


1) Input validation error (CVE-ID: CVE-2015-5589)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The phar_convert_to_other function in ext/phar/phar_object.c in PHP before 5.4.43, 5.5.x before 5.5.27, and 5.6.x before 5.6.11 does not validate a file pointer before a close operation, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted TAR archive that is mishandled in a Phar::convertToData call.
