CVE-2016-4752

CVE-2016-4752 affects Apple OS X pre-10.12. The issue is in the SecKeyDeriveFromPassword function, where the CF_RETURNS_RETAINED keyword was not used, enabling memory handling that may allow memory content to be leaked or exposed during key derivation. The connected Apple security content confirm...

RUSTSEC-2016-0005 rust-crypto is unmaintained; switch to a modern alternative

The rust-crypto crate has not seen a release or GitHub commit since 2016, and its author is unresponsive. NOTE: The old rust-crypto crate with hyphen should not be confused with similarly named new RustCrypto GitHub Org without hyphen. The GitHub Org is actively maintained. We recommend you switc...

So I lost my OpenBSD FDE password

The other day I set up a new OpenBSD instance with a nice RAID array, encrypted with Full Disk Encryption. And promptly proceeded to forget part of the passphrase. We know things get interesting when I lose a password. I did a weak attempt at finding some public bruteforce tool, and found nothing...

OpenSSL Cryptographic Algorithm Cracking Vulnerability

OpenSSL is a general-purpose open source cryptographic library that implements Secure Sockets Layer and Secure Transport Layer protocols and can support a variety of cryptographic algorithms, including symmetric ciphers, hashing algorithms, secure hashing algorithms, and so on. OpenSSL there is a...

NIST Seeking Public Comment on SHA-3 Crypto Algorithm

The National Institute of Standards and Technology NIST is inviting the public to analyze and comment on its Secure Hash Algorithm-3 SHA-3, the latest iteration of cryptographic hash functions endorsed and published by the U.S. standards agency in order to protect the integrity of electronic...

krb5: PKINIT null pointer deref leads to DoS

The pkinitserverreturnpadata function in plugins/preauth/pkinit/pkinitsrv.c in the PKINIT implementation in the Key Distribution Center KDC in MIT Kerberos 5 aka krb5 before 1.10.4 attempts to find an agility KDF identifier in inappropriate circumstances, which allows remote attackers to cause a...

FreeBSD : krb5 -- multiple checksum handling vulnerabilities (0d57c1d9-03f4-11e0-bf50-001a926c7637)

The MIT Kerberos team reports : MIT krb incorrectly accepts an unkeyed checksum with DES session keys for version 2 RFC 4121 of the GSS-API krb5 mechanism. An unauthenticated remote attacker can forge GSS tokens that are intended to be integrity-protected but unencrypted, if the targeted...

FreeBSD : krb5 -- RFC 3961 key-derivation checksum handling vulnerability (1d193bba-03f6-11e0-bf50-001a926c7637)

The MIT Kerberos team reports : MIT krb5 releases incorrectly accepts RFC 3961 key-derivation checksums using RC4 keys when verifying AD-SIGNEDPATH and AD-KDC-ISSUED authorization data. An authenticated remote attacker that controls a legitimate service principal has a 1/256 chance of forging the...

CVE-2010-4020

MIT Kerberos 5 aka krb5 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a 1 AD-SIGNEDPATH or 2 AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte...
