Experts Discover Flaw in U.S. Govt's Chosen Quantum-Resistant Encryption Algorithm

A group of researchers has revealed what it says is a vulnerability in a specific implementation of CRYSTALS-Kyber, one of the encryption algorithms chosen by the U.S. government as quantum-resistant last year. The exploit relates to "side-channel attacks on up to the fifth-order masked...

FreeBSD : curl -- multiple vulnerabilities (be233fc6-bae7-11ed-a4fb-080027f5fec9)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the be233fc6-bae7-11ed-a4fb-080027f5fec9 advisory. - A cleartext transmission of sensitive information vulnerability exists in curl v7.88.0 that...

CVE-2023-23916

An allocation of resources without limits or throttling vulnerability exists in curl v7.88.0 based on the "chained" HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable "links" in this...

[SECURITY] Fedora 36 Update: openssl-3.0.8-1.fc36

K14363514: OpenSSL vulnerability CVE-2017-3736

Security Advisory Description There is a carry propagating bug in the x8664 Montgomery squaring procedure in OpenSSL before 1.0.2m and 1.1.0 before 1.1.0g. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perfo...

K83623027: OpenSSL vulnerability CVE-2021-3449

Security Advisory Description An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signaturealgorithms extension where it was present in the initial ClientHello, but includes a...

Abstract: Artificial Intelligence AI has been a game-changer in many industries, and cybersecurity is no exception. AI has revolutionized the way organizations approach security, providing new and innovative solutions for detecting and mitigating cyber threats. However, with its increasing use, i...

Dell EMC Unity Encryption Issue Vulnerability

Dell EMC Unity is a unified storage array product from Dell, a U.S. company. versions prior to Dell EMC Unity 5.2.0.0.5.173 have an encryption issue vulnerability that stems from the use of corrupted encryption algorithms, which can be exploited by a remote, unauthenticated attacker to obtain...

CURL-CVE-2023-23916 HTTP multi-header compression denial of service

curl supports "chained" HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was capped, but the cap was implemented on a per-header basis allowing a...

SUSE CVE-2009-0049

Belgian eID middleware eidlib 2.6.0 and earlier does not properly check the return value from the OpenSSL EVPVerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys, a similar vulnerability to...

SUSE CVE-2015-0291

The sigalgs implementation in t1lib.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service NULL pointer dereference and daemon crash by using an invalid signaturealgorithms extension in the ClientHello message during a renegotiation...
