Name of the Vulnerable Software and Affected Versions HHVM versions 4.172.0 and all prior versions

Description The issue arises from HHVM using TLS 1.0 for secure connections when handling tls:// URLs in the stream extension. TLS 1.0 has numerous published vulnerabilities and is deprecated. Applications that call stream socket server or stream socket client functions with a URL starting with tls:// are affected.

Recommendations For HHVM versions 4.172.0 and all prior versions, update to a version that replaces TLS 1.0 with TLS 1.3, such as HHVM 4.153.4, 4.168.2, 4.169.2, 4.170.2, 4.171.1, 4.172.1, or 4.173.0. As a temporary workaround, consider avoiding the use of tls:// URLs in the stream extension until a patch is available. Restrict access to the stream socket server and stream socket client functions to minimize the risk of exploitation.
