CVE Severity Published▾ Status Exploitation Description
CVE-2025-13151 High 2026-01-07 Not applicable No public exploit Stack-based buffer overflow in libtasn1 version: v4.20.0. The function fails to validate the size of input data resulting in a buffer overflow in asn1_expend_octet_string.
CVE-2021-46848 Critical 2022-10-24 Not applicable No public exploit GNU Libtasn1 before 4.19.0 has an ETYPE_OK off-by-one array size check that affects asn1_encode_simple_der.
CVE-2018-1000654 Medium 2018-08-20 Not applicable No public exploit GNU Libtasn1-4.13 libtasn1-4.13 version libtasn1-4.13, libtasn1-4.12 contains a DoS, specifically CPU usage will reach 100% when running asn1Paser against the POC due to an issue in _asn1_expand_object_id(p_tree), after a long time, the program will be killed. This attack appears to be exploitable via parsing a crafted file.
CVE-2018-6003 High 2018-01-22 Not applicable No public exploit An issue was discovered in the _asn1_decode_simple_ber function in decoding.c in GNU Libtasn1 before 4.13. Unlimited recursion in the BER decoder leads to stack exhaustion and DoS.
CVE-2017-10790 High 2017-07-02 Not applicable No public exploit The _asn1_check_identifier function in GNU Libtasn1 through 4.12 causes a NULL pointer dereference and crash when reading crafted input that triggers assignment of a NULL value within an asn1_node structure. It may lead to a remote denial of service attack.
CVE-2017-6891 High 2017-05-22 Outside Waratek scope No public exploit Two errors in the "asn1_find_node()" function (lib/parser_aux.c) within GnuTLS libtasn1 version 4.10 can be exploited to cause a stacked-based buffer overflow by tricking a user into processing a specially crafted assignments file via the e.g. asn1Coding utility.
CVE-2016-4008 Medium 2016-05-05 Not applicable No public exploit The _asn1_extract_der_octet function in lib/decoding.c in GNU Libtasn1 before 4.8, when used without the ASN1_DECODE_FLAG_STRICT_DER flag, allows remote attackers to cause a denial of service (infinite recursion) via a crafted certificate.
CVE-2015-3622 Medium 2015-05-12 Not applicable No public exploit 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.
CVE-2015-2806 High 2015-04-10 Not applicable No public exploit Stack-based buffer overflow in asn1_der_decoding in libtasn1 before 4.4 allows remote attackers to have unspecified impact via unknown vectors.
CVE-2014-3469 Medium 2014-06-05 Not applicable No public exploit The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument.
CVE-2014-3468 High 2014-06-05 Not applicable No public exploit The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data.
CVE-2014-3467 Medium 2014-06-05 Not applicable No public exploit Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1 before 3.6, as used in GnuTLS, allow remote attackers to cause a denial of service (out-of-bounds read) via crafted ASN.1 data.
CVE-2012-1569 Medium 2012-03-26 Not applicable No public exploit The asn1_get_length_der function in decoding.c in GNU Libtasn1 before 2.12, as used in GnuTLS before 3.0.16 and other products, does not properly handle certain large length values, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly have unspecified other impact via a crafted ASN.1 structure.
