EUVD-2026-18356

An issue was discovered in Mbed TLS 3.x before 3.6.6. An out-of-bounds read vulnerability in mbedtlsccmfinish in library/ccm.c allows attackers to obtain adjacent CCM context data via invocation of the multipart CCM API with an oversized taglen parameter. This is caused by missing validation of t...

CVE-2026-34876

The CVE-2026-34876 issue affects Mbed TLS 3.x prior to 3.6.6. An out-of-bounds read in mbedtls_ccm_finish() (library/ccm.c) can reveal adjacent CCM context data when the multipart CCM API is invoked with an oversized tag_len. Root cause: missing validation of tag_len against the internal 16-byte ...

Buffer Overflow

Overview Affected versions of this package are vulnerable to Buffer Overflow via the FFDH public key export in the psaexportpublickey function. An attacker can execute arbitrary code or cause a denial of service by sending specially crafted input to the affected process. Remediation Upgrade mbedt...

curl: SSL options ISSUERCERT, EC_CURVES and CRLFILE silently ignored by non-OpenSSL backends

Summary: The SSL options ISSUERCERT, ECCURVES and CRLFILE are silently ignored for e.g. the mbedTLS backend, which allows MITM attacks for the ISSUERCERT and CRLFILE bug, and can reduce the security and compliance by ignoring the specified curve for the ECCURVES bug. Affected version Tested with...

A Lucky 13 timing side channel in mbedtlsssldecryptbuf in library/sslmsg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length...

JLSEC-2025-233 Padding oracle through timing of cipher error reporting

Vulnerability In symmetric encryption modes that involve padding, if an attacker can submit ciphertexts for decryption and learn whether the padding is valid, this provides partial information about the plaintext. If the attacker can also submit input that the victim encrypts together with a...

Siemens SIMATIC S7-1500 Improper Validation of Certificate with Host Mismatch (CVE-2024-2466)

libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified hostname was given as an IP address, therefore completely skipping the certificate...

CVE-2025-64429

DuckDB 1.4.0–pre-1.4.2 encryption implementation is vulnerable due to multiple cryptographic weaknesses: insecure RNG (pcg32 fallback), possible memory wipe omission (memset) leaving secrets, and header manipulation could downgrade from GCM to CTR, bypassing integrity. There may also be unhandled...
