    Summary: Processing of maliciously crafted length fields causes memory allocation SIGABRTs

    Details: Affected versions of this crate tried to preallocate a vector for an arbitrary amount of bytes announced by the ASN.1-DER length field without further checks. This allows an attacker to trigger a SIGABRT by creating length fields that announce more bytes than the allocator can provide. The flaw was corrected by not preallocating memory.
