encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...

ROS-20260710-73-0018

The vulnerability of the Go programming language’s encoding/ASN1 component is related to the lack of memory release after the effective lifespan of the component. Exploiting this vulnerability can allow a remote attacker to cause a service failure...

encoding/asn1: Parsing DER payload can cause memory exhaustion in encoding/asn1

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...
