Hello gophers,

Version v0.0.0-20210520170846-37e1c6afe023 of golang.org/x/net fixes a vulnerability in the golang.org/x/net/html package which could cause a denial of service.

An attacker can craft an input to ParseFragment that would cause it to enter an infinite loop and never return.

This issue was discovered by OSS-Fuzz and reported to us by Andrew Thornton <ar...@cantab.net>, and is tracked as CVE-2021-33194.

Cheers,
Filippo on behalf of the Go team
