Name of the Vulnerable Software and Affected Versions asn1c version 0.9.28

Description The issue allows remote attackers to cause a denial of service, resulting in a segmentation fault, by providing a crafted .asn1 file. This is due to a problem in the asn1f lookup symbol impl function.

Recommendations For version 0.9.28, consider avoiding the use of crafted .asn1 files until a patch is available. As a temporary workaround, restrict the input to the asn1f lookup symbol impl function to prevent the denial of service.
