PVK files with abnormally large length or salt fields can cause an integer overflow which can result in an OOB read and heap corruption. However this is an rarely used format and private key files do not normally come from untrusted sources the security implications not significant. Fix by limiting PVK length field to 100K and salt to 10K: these should be more than enough to cover any files encountered in practice. Issue reported by Guido Vranken. Reviewed-by: Rich Salz <rs...@...nssl.org> As per the notes in the commit we do not see the security implications as significant and therefore we are treating this as a bug and will not be issuing a CVE.
