SUSE CVE-2026-55737

Signed to Unsigned Conversion Error and Out-of-bounds Write vulnerability in Erlang OTP erts allows an attacker who can supply a crafted Erlang external term format ETF binary to binarytoterm/1 to corrupt the BEAM heap pointer and crash the virtual machine. When decoding a LARGETUPLEEXT term, the...

SUSE CVE-2026-55953

The Erlang/OTP ssl TLS 1.2 and earlier and DTLS client does not verify that the cipher suite selected by the server in ServerHello was among the suites offered by the client in ClientHello. The client-side tlshandshake:hello/5 handler validates the negotiated protocol version and the downgrade...

SUSE CVE-2026-58227

The Erlang/OTP ssl application does not detect cycles when reconstructing an incomplete peer certificate chain during a TLS or DTLS handshake. In sslcertificate:handleincompletechain/5, the received chain is passed to sslcertificate:buildcertificatechain/5, which walks issuer relationships via...

SUSE CVE-2026-59250

Classic buffer overflow in the Erlang/OTP megaco flex scanner C driver allows a remote unauthenticated attacker to corrupt the driver's memory and potentially achieve remote code execution or a denial-of-service crash by sending a single text-encoded H.248/Megaco message containing an oversized...

SUSE CVE-2026-59251

Allocation of resources without limits in Erlang/OTP publickey certificate path validation allows a remote unauthenticated attacker to cause denial of service by sending a crafted X.509 certificate chain during the TLS handshake. During RFC 5280 policy processing in publickey:pkixpathvalidation/3...

CVE-2026-47078

A flaw was found in the Erlang OTP stdlib zip module. The zip:unzip and zip:extract functions, which handle archive extraction, are vulnerable to a relative path traversal attack. A remote attacker could craft a malicious zip archive containing specially formed entry names. When processed, this...

CVE-2026-55953

A flaw was found in the Erlang/OTP ssl client. This vulnerability allows an on-path attacker to bypass server authentication in TLS 1.2 and earlier and DTLS connections. By tricking the client into accepting an unoffered anonymous cipher suite, the attacker can complete the handshake without a...

CVE-2026-55737

A flaw was found in Erlang OTP. A remote attacker can exploit a vulnerability in the Erlang external term format ETF decoder by providing a specially crafted binary to the binarytoterm/1 function. This manipulation of data types during processing can corrupt the system's memory, leading to an...

CVE-2026-59251

A flaw was found in Erlang/OTP's publickey application. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted X.509 certificate chain during a Transport Layer Security TLS handshake. This causes the certificate path validation process to consume excessiv...

CVE-2026-54890

A flaw was found in Erlang/OTP. A remote attacker can exploit an integer underflow vulnerability in the External Term Format ETF decoder, specifically within the binarytoterm function. By sending a specially crafted ETF payload with a zero-length BITBINARYEXT tag, the attacker can trigger an...

cowboy: Cowboy: Denial of Service via HTTP/1.1 duplicate header names

A flaw was found in Cowboy. An unauthenticated remote attacker can exploit this vulnerability by sending multiple HTTP/1.1 header lines with the same name. This bypasses the maxheaders limit, causing the connection process memory to grow uncontrollably. This can lead to memory exhaustion and a...
