Siemens SCALANCE OpenSSL Allocation of Resources Without Limits or Throttling (CVE-2023-2650)

Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be very slow. Impact summary: Applications that use OBJobj2txt directly, or use any of the OpenSSL subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience...

Siemens SCALANCE OpenSSL Out-of-bounds Read (CVE-2022-4203)

A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate...

Siemens SCALANCE OpenSSL NULL Pointer Dereference (CVE-2023-0216)

An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2iPKCS7, d2iPKCS7bio or d2iPKCS7fp functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in...

Siemens SCALANCE OpenSSL NULL Pointer Dereference (CVE-2023-0401)

A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail...

netty: SniHandler 16MB allocation leads to OOM

A flaw was found in Netty's SniHandler while navigating TLS handshake which may permit a large heap allocation if the handler did not have a timeout configured. This issue may allow an attacker to send a client hello packet which would cause the server to buffer large amounts of data per...

golang: crypto/tls: lack of a limit on buffered post-handshake

A flaw was found in Golang. QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth. With the fix, connections now consistently reject messages larger than 65KiB in size...

golang: crypto/tls: panic when processing post-handshake message on QUIC connections

A flaw was found in Golang. Processing an incomplete post-handshake message for a QUIC connection caused a panic...
