Name of the Vulnerable Software and Affected Versions GNU Libtasn1 versions prior to 4.8

Description The issue allows remote attackers to cause a denial of service, specifically an infinite recursion, through a crafted certificate. This occurs when the asn1 extract der octet function in lib/decoding.c is used without the ASN1 DECODE FLAG STRICT DER flag.

Recommendations For versions prior to 4.8, update to version 4.8 or later to resolve the issue. As a temporary workaround, consider using the ASN1 DECODE FLAG STRICT DER flag when utilizing the asn1 extract der octet function to minimize the risk of exploitation.
