An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name SAN extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect...

JLSEC-2026-700 Out-of-bounds heap read during SM2/SM3 certificate signature verification

Out-of-bounds heap read during SM2/SM3 certificate signature verification. When parsing a certificate with an SM3wSM2 signature, the Subject Key Identifier computation reads the trailing 65 bytes of the public key without checking that the key is at least that long. A public key shorter than 65...

1-byte OOB heap read in wcPKCS7DecodeEnvelopedData via zero-length encrypted content. A vulnerability existed in wolfSSL 5.8.4 and earlier, where a 1-byte out-of-bounds heap read in wcPKCS7DecodeEnvelopedData could be triggered by a crafted CMS EnvelopedData message with zero-length encrypted...

JLSEC-2026-708

Heap Overflow in TLS 1.3 ECH parsing. An integer underflow existed in ECH extension parsing logic when calculating a buffer length, which resulted in writing beyond the bounds of an allocated buffer. Note that in wolfSSL, ECH is off by default, and the ECH standard is still evolving...

Remotely executed SEGV and out of bounds read allows malicious packet sender to crash or cause an out of bounds read via sending a malformed packet with the correct length...

JLSEC-2026-719

A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wcPKCS7DecryptOri function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo ORI recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer...

EUVD-2026-44428

A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames e.g., PING, PONG, CLOSE contain a payload of 125 bytes or less. A remote, unauthenticated attacker...

EUVD-2026-44341

A heap buffer over-read vulnerability was discovered in libsoup's versions: libsoup 3.0 to 3.7.0 HTTP/2 connection tracking framework. When the library processes an HTTP/2 GOAWAY frame, it improperly handles the "Additional Debug Data" payload by assuming the data stream is a safely NUL-terminate...

EUVD-2026-44504

Tornado is a Python web framework and asynchronous networking library. Prior to 6.5.6, the optional native extension tornado.speedups implemented websocketmask without validating that the mask argument is exactly four bytes, allowing the C function to read up to three bytes beyond the provided...

AZL-92400 CVE-2026-15711 affecting package libsoup 3.4.4-16

A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames e.g., PING, PONG, CLOSE contain a payload of 125 bytes or less.

CVE-2026-45756

Summary (CVE-2026-45756) : The Symfony JsonPath component allows attacker-controlled regular expressions in the match() and search() filters to be compiled directly into PCRE without length or backtracking limits, enabling catastrophic backtracking (ReDoS) and denial of service. Affected are Symf...

USN-8542-1: Dnsmasq vulnerabilities

Yiwei Hou discovered that Dnsmasq incorrectly handled logging of DS or DNSKEY. A remote attacker could possibly use this issue to cause a denial of service. CVE-2026-12725 It was discovered that Dnsmasq incorrectly validated the length of fixed-length DNS record fields when parsing NS section...

CVE-2026-59198

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0...

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0...

CVE-2026-59198 Pillow TGA RLE encoder can serialize up to ~57 KB of adjacent heap data into generated images

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0...

BIT-PROMETHEUS-2026-42154 Prometheus: remote read endpoint allows denial of service via crafted snappy payload

Prometheus is an open-source monitoring system and time series database. Prior to versions 3.5.3 and 3.11.3, the remote read endpoint /api/v1/read does not validate the declared decoded length in a snappy-compressed request body before allocating memory. An unauthenticated attacker can send a sma...

CVE-2026-10672 Unterminated URI buffer causes out-of-bounds read in LwM2M firmware pull (Package URI)

subsys/net/lib/lwm2m/lwm2mpullcontext.c copied the firmware-update Package URI into a fixed static buffer context.uri, size CONFIGLWM2MSWMGMTPACKAGEURILEN, default 128 with memcpycontext.uri, uri, LWM2MPACKAGEURILEN, copying exactly the destination size with no length validation. The...

CVE-2026-59246 Zero-length HTTP/2 CONTINUATION frames bypass Mint's header-block byte-size cap and exhaust client memory

Allocation of resources without limits vulnerability in elixir-mint mint allows a remote HTTP/2 server to exhaust memory on the client host and cause a denial of service. The Mint.HTTP2.handlecontinuation/3 function in lib/mint/http2.ex accumulates the header-block fragment carried by each HTTP/2...
