Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, the openssl extension PEM sealing code did not check the return value of the OpenSSL sealing function, which could lead to a crash of the PHP interpreter, related to an interpretation conflict for a negative number in ext/openssl/openssl.c, and an OpenSSL documentation omission.
