Vetor base

AV:N/AC:M/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions GNU Libtasn1 versions prior to 4.5

Description The issue allows remote attackers to cause a denial of service, specifically an out-of-bounds heap read, by providing a crafted certificate. This is related to the asn1 extract der octet function in lib/decoding.c.

Recommendations For GNU Libtasn1 versions prior to 4.5, update to version 4.5 or later to resolve the issue. As a temporary workaround, consider restricting the processing of crafted certificates to minimize the risk of exploitation.
