JLSEC-2026-724 X.509 date buffer overflow in `wolfSSL_X509_notAfter` / `wolfSSL_X509_notBefore`
X.509 date buffer overflow in wolfSSLX509notAfter / wolfSSLX509notBefore. A buffer overflow may occur when parsing date fields from a crafted X.509 certificate via the compatibility layer API. This is only triggered when calling these two APIs directly from an application, and does not affect TLS...

Integer underflow in wolfSSL packet sniffer = 5.8.4 allows an attacker to cause a buffer overflow in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by sslDecodePacket. The underflow wraps a 16-bit length to a large...

JLSEC-2026-657 Deno: BYONM module resolution allows `package.json` main path traversal to bypass `--allow-read` restrictions
Summary When Deno was run in BYONM mode nodeModulesDir: "manual", the module resolver did not validate that a package's resolved entrypoint stayed within its nodemodules// directory. A malicious package.json whose main field contained .. segments was able to resolve to an arbitrary path on disk,...

In rsync 3.0.1 through 3.4.1, receivexattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X aka --xattrs. On Linux, many but not all common configurations are vulnerable. Non-Linux platforms are more widely vulnerable...
