| CVE | Severidad | EPSS | Explotación activa | Publicada | Descripción |
|---|---|---|---|---|---|
| CVE-2025-13151 | Alta (7.5) | 1.1% | — | 7 ene 2026 | 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-2024-12243 | Media (5.3) | 1.3% | — | 10 feb 2025 | A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased… |
| CVE-2024-12133 | Media (5.3) | 1.1% | — | 10 feb 2025 | A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the… |
| CVE-2021-46848 | Crítica (9.1) | 2.2% | — | 24 oct 2022 | 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 | Media (5.5) | 2.0% | — | 20 ago 2018 | 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… |
| CVE-2018-6003 | Alta (7.5) | 2.8% | — | 22 ene 2018 | 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 | Alta (7.5) | 5.0% | — | 2 jul 2017 | 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… |
| CVE-2017-6891 | Alta (8.8) | 5.6% | — | 22 may 2017 | 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… |
| CVE-2016-4008 | Media (5.9) | 26% | — | 5 may 2016 | 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… |
| CVE-2015-3622 | Media (4.3) | 33% | — | 12 may 2015 | 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 | Alta (10) | 7.7% | — | 10 abr 2015 | 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 | Media (5) | 3.8% | — | 5 jun 2014 | 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… |
| CVE-2014-3468 | Alta (7.5) | 3.8% | — | 5 jun 2014 | 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… |
| CVE-2014-3467 | Media (5) | 6.8% | — | 5 jun 2014 | 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 | Media (5) | 4.4% | — | 26 mar 2012 | 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… |
