CVE-2023-24609 |
Matrix SSL 4.x through 4.6.0 and Rambus TLS Toolkit have a length-subtraction integer overflow for Client Hello Pre-Shared Key extension parsing in the TLS 1.3 server. An attacked device calculates an SHA-2 hash over at least 65 KB (in RAM). With a large number of crafted TLS messages, the CPU becomes heavily loaded. This occurs in tls13VerifyBinder and tls13TranscriptHashUpdate. Published: December 21, 2023; 11:15:08 PM -0500 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0:(not available) |
CVE-2022-46505 |
An issue in MatrixSSL 4.5.1-open and earlier leads to failure to securely check the SessionID field, resulting in the misuse of an all-zero MasterSecret that can decrypt secret data. Published: January 18, 2023; 11:15:11 AM -0500 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0:(not available) |
CVE-2022-43974 |
MatrixSSL 4.0.4 through 4.5.1 has an integer overflow in matrixSslDecodeTls13. A remote attacker might be able to send a crafted TLS Message to cause a buffer overflow and achieve remote code execution. This is fixed in 4.6.0. Published: January 09, 2023; 4:15:10 AM -0500 |
V4.0:(not available) V3.1: 9.8 CRITICAL V2.0:(not available) |
CVE-2019-16747 |
In MatrixSSL before 4.2.2 Open, the DTLS server can encounter an invalid pointer free (leading to memory corruption and a daemon crash) via a crafted incoming network message, a different vulnerability than CVE-2019-14431. Published: December 30, 2020; 4:15:12 PM -0500 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2019-13629 |
MatrixSSL 4.2.1 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or a remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because crypto/pubkey/ecc_math.c scalar multiplication leaks the bit length of the scalar. Published: October 03, 2019; 10:15:11 AM -0400 |
V4.0:(not available) V3.1: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2019-14431 |
In MatrixSSL 3.8.3 Open through 4.2.1 Open, the DTLS server mishandles incoming network messages leading to a heap-based buffer overflow of up to 256 bytes and possible Remote Code Execution in parseSSLHandshake in sslDecode.c. During processing of a crafted packet, the server mishandles the fragment length value provided in the DTLS message. Published: July 29, 2019; 6:15:12 PM -0400 |
V4.0:(not available) V3.1: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2019-13470 |
MatrixSSL before 4.2.1 has an out-of-bounds read during ASN.1 handling. Published: July 09, 2019; 5:15:11 PM -0400 |
V4.0:(not available) V3.0: 9.8 CRITICAL V2.0: 7.5 HIGH |
