Bleichenbacher's attack on PKCS #1 v1.5 padding for RSA in STM32 cryptographic firmware library software expansion for STM32Cube (UM1924). The vulnerability can allow one to use Bleichenbacher's oracle attack to decrypt an encrypted ciphertext by making successive queries to the server using the vulnerable library, resulting in remote information disclosure.

https://notcve.org/view.php?id=CVE-2018-5389
The Internet Key Exchange v1 main mode is vulnerable to offline dictionary or brute force attacks. Reusing a key pair across different versions and modes of IKE could lead to cross-protocol authentication bypasses. It is well known, that the aggressive mode of IKEv1 PSK is vulnerable to offline dictionary or brute force attacks. For the main mode, however, only an online attack against PSK authentication was thought to be feasible. This vulnerability could allow an attacker to recover a weak Pre-Shared Key or enable the impersonation of a victim host or network. • https://blogs.cisco.com/security/great-cipher-but-where-did-you-get-that-key https://my.f5.com/manage/s/article/K42378447 https://web-in-security.blogspot.com/2018/08/practical-dictionary-attack-on-ipsec-ike.html https://www.kb.cert.org/vuls/id/857035 https://www.usenix.org/system/files/conference/usenixsecurity18/sec18-felsch.pdf • CWE-521: Weak Password Requirements •
CVSS: 8.6EPSS: 0%CPEs: 1EXPL: 0CVE-2016-10142 – kernel - IPV6 fragmentation flaw
https://notcve.org/view.php?id=CVE-2016-10142
An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages. (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. • http://rhn.redhat.com/errata/RHSA-2017-0817.html http://www.securityfocus.com/bid/95797 http://www.securitytracker.com/id/1038256 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA43730 https://support.f5.com/csp/article/K57211290?utm_source=f5support&%3Butm_medium=RSS https://tools.ietf.org/html/draft-ietf-6man-deprecate-atomfrag-generation-08 https://tools.ietf.org/html/rfc8021 https://access.redhat.com/security/cve/CVE-2016-10142 https://bugzilla.redhat.com/show_ • CWE-17: DEPRECATED: Code CWE-406: Insufficient Control of Network Message Volume (Network Amplification) •
