CVE-2025-69419 Out of bounds write in PKCS12_get_friendlyname() UTF-8 conversion

Issue summary: Calling PKCS12getfriendlyname function on a maliciously crafted PKCS12 file with a BMPString UTF-16BE friendly name containing non-ASCII BMP code point can trigger a one byte write before the allocated buffer. Impact summary: The out-of-bounds write can cause a memory corruption...

CVE-2025-69419

CVE-2025-69419 is an OpenSSL vulnerability arising from PKCS12_get_friendlyname() processing of attacker-supplied PKCS#12 BMPString names. The root cause is in OPENSSL_uni2utf8(): during the second pass, bmp_to_utf8() forwards the remaining UTF-16 source byte count as the destination capacity to ...

CVE-2025-69418 Unauthenticated/unencrypted trailing bytes with low-level OCB function calls

Issue summary: When using the low-level OCB API directly with AES-NI orother hardware-accelerated code paths, inputs whose length is not a multipleof 16 bytes can leave the final partial block unencrypted and unauthenticated.Impact summary: The trailing 1-15 bytes of a message may be exposed...

EUVD-2025-206397

Issue summary: Writing large, newline-free data into a BIO chain using the line-buffering filter where the next BIO performs short writes can trigger a heap-based out-of-bounds write. Impact summary: This out-of-bounds write can cause memory corruption which typically results in a crash, leading ...

CVE-2025-68160

CVE-2025-68160 describes a heap-based out-of-bounds write in OpenSSL’s BIO_f_linebuffer filter when a BIO chain writes large, newline-free data with subsequent short writes. This can cause memory corruption and a Denial of Service. Affected products/versions include OpenSSL 3.6, 3.5, 3.4, 3.3, 3....

CVE-2025-69418

CVE-2025-69418 affects OpenSSL when using the low-level OCB API (CRYPTO_ocb128_encrypt/decrypt) with non-block-aligned lengths on hardware-accelerated builds. The trailing 1–15 bytes of a message may be left unencrypted and unauthenticated, exposing or tampering with data. The issue does not affe...

CVE-2025-66199

CVE-2025-66199 affects OpenSSL TLS 1.3 certificate compression. A peer’s CompressedCertificate can cause an unbounded heap buffer growth prior to decompression, enabling per-connection allocations up to ~22 MiB and degraded service or resource exhaustion. Affected: OpenSSL 3.6, 3.5, 3.4 and 3.3 (...

CVE-2025-66199 TLS 1.3 CompressedCertificate excessive memory allocation

Issue summary: A TLS 1.3 connection using certificate compression can be forced to allocate a large buffer before decompression without checking against the configured certificate size limit. Impact summary: An attacker can cause per-connection memory allocations of up to approximately 22 MiB and...
