OpenSSL 加密问题漏洞

OpenSSL is an open source general-purpose cryptographic library from the Openssl team capable of implementing the Secure Sockets Layer SSLv2/v3 and Secure Transport Layer TLSv1 protocols. The product supports multiple encryption algorithms, including symmetric ciphers, hashing algorithms, secure...

UBUNTU-CVE-2022-1434

The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipie...

OpenSSL 3.0.0 < 3.0.3 Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 3.0.3. It is, therefore, affected by multiple vulnerabilities as referenced in the 3.0.3 advisory. - The OPENSSLLHflush function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed has...

FreeBSD Buffer Overflow Vulnerability (CNVD-2020-32360)

FreeBSD is a set of Unix-like operating systems from the FreeBSD Foundation. A buffer overflow vulnerability exists in the cryptodev module in FreeBSD versions prior to 12.1-STABLE r356911 and prior to 12.1-RELEASE p5, which stems from a program that fails to adequately validate the length of a...

FreeBSD-SA-20:16.cryptodev

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 ============================================================================= FreeBSD-SA-20:16.cryptodev Security Advisory The FreeBSD Project Topic: Insufficient cryptodev MAC key length check Category: core Module: cryptodev Announced: 2020-05-12...

FreeBSD -- Insufficient cryptodev MAC key length check

Problem Description: Requests to create cryptography sessions using a MAC did not validate the user-supplied MAC key length. The cryptodev module allocates a buffer whose size is this user-suppled length. Impact: An unprivileged process can trigger a kernel panic...

Bouncy Castle BKS-V1 keystore files vulnerable to trivial hash collisions

Overview Bouncy Castle BKS version 1 keystore files use an HMAC that is only 16 bits long, which can allow an attacker to compromise the integrity of a BKS-V1 keystore. Description Bouncy Castle is a cryptographic library for C and Java applications, including Android applications. BKS is a...
