Does permessage-deflate extension bug affect 6.2.2

Description

Is the permessage-deflate extension bug that was fixed in 7.4.4 also present in 6.2.2?

I realize the 6.x branch is older (and unmaintained?) but ws is a sub-dependency of a library we cannot upgrade due to runtime environment reasons. The static analysis tool we are forced to use is flagging 6.2.2 as susceptible to this bug, though I cannot find any mention of it outside of the tool's reporting.

If the bug is still present, would it be possible to get the fix backported to the 6.x line?

Version 6.2.2 is not affected. The bug fixed in version 7.4.4 was introduced in version 7.4.3 with #1840.
