Описание
Parsing a maliciously crafted DER payload could allocate large amounts of memory, causing memory exhaustion.
A memory exhaustion flaw has been discovered in the golang encoding/asn1 module. Within parseSequenceOf, reflect.MakeSlice is being used to pre-allocate a slice that is needed in order to fully validate the given DER payload. The size of the slice allocated are also multiple times larger than the input DER. As a result, a malicious actor can craft a big empty DER payload, resulting in an unnecessary large allocation of memories. This can be a way to cause memory exhaustion.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
