Insufficient Entropy

Overview All versions of parsel use an insecure key derivation function. The package runs keys of arbitrary lengths through one round of SHA256 hashing for key stretching. This allows for the use of keys of insufficient entropy with inappropriate key stretching. Recommendation The package is...

Insecure Encryption

Overview parsel is a gem to encrypt and decrypt data with a given key. Affected versions of this package are vulnerable to Insecure Encryption. It contains a weak key derivation function, in which a key of arbitrary length is run through one round of SHA256 to gain key material of the correct...

Mozilla: Stack buffer overflow in HKDF output

A flaw was discovered in both Firefox and Thunderbird where 4 bytes of a HMAC output could be written past the end of a buffer stored on the memory stack. This could allow an attacker to execute arbitrary code or lead to a crash. This flaw can be exploited over the network...

CVE-2018-20958

The Bluetooth Low Energy BLE subsystem on Tapplock devices before 2018-06-12 relies on Key1 and SerialNo for unlock operations; however, these are derived from the MAC address, which is broadcasted by the device...

Pyrit - The Famous WPA Precomputed Cracker

Pyrit allows you to create massive databases of pre-computed WPA/WPA2-PSK authentication phase in a space-time-tradeoff. By using the computational power of Multi-Core CPUs and other platforms through ATI-Stream,Nvidia CUDA and OpenCL, it is currently by far the most powerful attack against one o...

VSHG aims to provide a memory / hardware resistant reinforcement to GnuPG's standared s2k key-derivation-function + a simplified interface for symmetric encryption . About VSHG VSHG Very secure hash generator is a standalone Addon for GnuPG Gnu privacy guard . It is written as a shell script and ...

strongswan -- Fix Denial-of-Service Vulnerability strongSwan (CVE-2018-10811, CVE-2018-5388)

strongSwan security team reports: A denial-of-service vulnerability in the IKEv2 key derivation was fixed if the openssl plugin is used in FIPS mode and HMAC-MD5 is negotiated as PRF which is not FIPS-compliant. So this should only affect very specific setups, but in such configurations all...

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...
