| CVE-2026-118374 | 1 Openbsd | 1 Libressl | 2026-10-28 | 5.9 Medium |
| LibreSSL ocspcheck through 4.4.0 contains a memory exhaustion vulnerability that allows malicious OCSP responders to exhaust memory by sending unbounded HTTP responses. Attackers controlling the responder or intercepting plain HTTP AIA OCSP traffic can stream endless headers or body data to http_head_read() and http_body_read(), denying certificate status checks. | ||||
| CVE-2026-118373 | 1 Openbsd | 1 Libressl | 2026-10-28 | 3.7 Low |
| LibreSSL ocspcheck through 4.4.0 contains a cleartext transmission vulnerability because url2host() discards the OCSP URL scheme and http_alloc() only selects TLS for port 443. On-path network attackers can read OCSP requests sent to https responder URLs on non-443 ports, exposing certificate serial numbers, issuer hashes, and nonces. | ||||
| CVE-2026-118372 | 1 Openbsd | 1 Libressl | 2026-10-28 | 3.7 Low |
| LibreSSL ocspcheck through 4.4.0 contains a CRLF injection vulnerability that allows attackers to inject HTTP headers by embedding CR/LF sequences in a certificate's AIA OCSP URI path. Because url2host() copies the path without rejecting control characters and http_open() places it in the POST request line, attackers can inject headers or split OCSP requests sent to the responder host. | ||||
| CVE-2026-118371 | 1 Openbsd | 1 Libressl | 2026-10-28 | 3.7 Low |
| LibreSSL through 4.4.0 contains a CRLF injection vulnerability in the libcrypto OCSP_sendreq_new() and OCSP_parse_url() functions, which write unvalidated request paths into the OCSP POST request line. Attackers can embed carriage return and line feed characters in a certificate's Authority Information Access OCSP URI to inject HTTP headers or split requests sent to responders and proxies. | ||||
| CVE-2017-8301 | 1 Openbsd | 1 Libressl | 2025-04-20 | N/A |
| LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx. | ||||
| CVE-2014-9424 | 1 Openbsd | 1 Libressl | 2025-04-12 | N/A |
| Double free vulnerability in the ssl_parse_clienthello_use_srtp_ext function in d1_srtp.c in LibreSSL before 2.1.2 allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering a certain length-verification error during processing of a DTLS handshake. | ||||
| CVE-2022-48437 | 1 Openbsd | 2 Libressl, Openbsd | 2025-02-10 | 5.3 Medium |
| An issue was discovered in x509/x509_verify.c in LibreSSL before 3.6.1, and in OpenBSD before 7.2 errata 001. x509_verify_ctx_add_chain does not store errors that occur during leaf certificate verification, and therefore an incorrect error is returned. This behavior occurs when there is an installed verification callback that instructs the verifier to continue upon detecting an invalid certificate. | ||||
| CVE-2021-46880 | 1 Openbsd | 2 Libressl, Openbsd | 2025-02-07 | 9.8 Critical |
| x509/x509_verify.c in LibreSSL before 3.4.2, and OpenBSD before 7.0 errata 006, allows authentication bypass because an error for an unverified certificate chain is sometimes discarded. | ||||
| CVE-2023-35784 | 1 Openbsd | 2 Libressl, Openbsd | 2024-12-17 | 9.8 Critical |
| A double free or use after free could occur after SSL_clear in OpenBSD 7.2 before errata 026 and 7.3 before errata 004, and in LibreSSL before 3.6.3 and 3.7.x before 3.7.3. NOTE: OpenSSL is not affected. | ||||
| CVE-2021-41581 | 1 Openbsd | 1 Libressl | 2024-11-21 | 5.5 Medium |
| x509_constraints_parse_mailbox in lib/libcrypto/x509/x509_constraints.c in LibreSSL through 3.4.0 has a stack-based buffer over-read. When the input exceeds DOMAIN_PART_MAX_LEN, the buffer lacks '\0' termination. | ||||
| CVE-2019-25049 | 2 Linux, Openbsd | 2 Linux Kernel, Libressl | 2024-11-21 | 7.1 High |
| LibreSSL 2.9.1 through 3.2.1 has an out-of-bounds read in asn1_item_print_ctx (called from asn1_template_print_ctx). | ||||
| CVE-2019-25048 | 2 Linux, Openbsd | 2 Linux Kernel, Libressl | 2024-11-21 | 7.1 High |
| LibreSSL 2.9.1 through 3.2.1 has a heap-based buffer over-read in do_print_ex (called from asn1_item_print_ctx and ASN1_item_print). | ||||
| CVE-2018-8970 | 1 Openbsd | 1 Libressl | 2024-11-21 | N/A |
| The int_x509_param_set_hosts function in lib/libcrypto/x509/x509_vpm.c in LibreSSL 2.7.0 before 2.7.1 does not support a certain special case of a zero name length, which causes silent omission of hostname verification, and consequently allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate. NOTE: the LibreSSL documentation indicates that this special case is supported, but the BoringSSL documentation does not. | ||||
| CVE-2018-12434 | 1 Openbsd | 1 Libressl | 2024-11-21 | N/A |
| LibreSSL before 2.6.5 and 2.7.x before 2.7.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. | ||||
| CVE-2015-5334 | 2 Openbsd, Opensuse | 2 Libressl, Opensuse | 2024-11-21 | 9.8 Critical |
| Off-by-one error in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (program crash) or possible execute arbitrary code via a crafted X.509 certificate, which triggers a stack-based buffer overflow. Note: this vulnerability exists because of an incorrect fix for CVE-2014-3508. | ||||
| CVE-2015-5333 | 2 Openbsd, Opensuse | 2 Libressl, Opensuse | 2024-11-21 | 7.5 High |
| Memory leak in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (memory consumption) via a large number of ASN.1 object identifiers in X.509 certificates. | ||||
