The _asn1_extract_der_octet function in lib/decoding.c in GNU Libtasn1 before 4.5 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a crafted certificate.
A heap-based buffer overflow flaw was found in the way the libtasn1 library decoded certain DER-encoded inputs. A specially crafted DER-encoded input could cause an application using libtasn1 to perform an invalid read, causing the application to crash.
