CVE-2015-5589
9.8
CRITICAL · CVSS 3.0 · EPSS 6.3% (pctl 93)
In your normal cycle
Critical by CVSS (9.8), but no sign of active exploitation.
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.
