CVE-2015-5589

CRITICAL 9.8EPSS 6.30%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (6.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
