Swift ASN.1 can be caused to crash when parsing certain BER/DER constructions. This crash is caused by a confusion in the ASN.1 library itself which assumes that certain objects can only be provided in either constructed or primitive forms, and will trigger a `preconditionFailure` if that constraint isn't met. Importantly, these constraints are actually required to be true in DER, but that correctness wasn't enforced on the early node parser side so it was incorrect to rely on it later on in decoding, which is what the library did. These crashes can be triggered when parsing any DER/BER format object. There is no memory-safety issue here: the crash is a graceful one from the Swift runtime. The impact of this is that it can be used as a denial-of-service vector when parsing BER/DER data from unknown sources, e.g. when parsing TLS certificates. Many thanks to @baarde for reporting this issue and providing the fix.

**How could an attacker exploit the vulnerability?** An authenticated attacker could make specially crafted API calls that lead to a Denial of Service.

**How could an attacker exploit this vulnerability?** An unauthenticated attacker could use a specially crafted application to leverage a protocol vulnerability in Windows Kerberos to perform a denial of service attack against the target.

**According to the CVSS metric, successful exploitation of this vulnerability has a high impact on availability (A:H). What does that mean for this vulnerability??** An attacker can send specially crafted packets which could impact availability of the service resulting in Denial of Service (DoS).

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**According to the CVSS metric, the attack vector is network (AV:N). How could an attacker exploit this vulnerability?** As an authenticated user, the attacker could send a specially crafted string of data over the network, causing the application to crash.

**According to the CVSS metric, successful exploitation of this vulnerability has a high impact on availability (A:H). What does that mean for this vulnerability??** An attacker can send specially crafted packets which could impact availability of the service resulting in Denial of Service (DoS).
