CVE-2019-6690

CVE-2019-6690 affects python-gnupg 0.4.3. A context-dependent flaw lets an attacker, if they control the GnuPG passphrase and the ciphertext is trusted, cause decryption of ciphertext other than intended (CWE-20: Improper Input Validation). Impact described in sources includes manipulation of enc...

CVE-2019-6690

python-gnupg 0.4.3 allows context-dependent attackers to trick gnupg to decrypt other ciphertext than intended. To perform the attack, the passphrase to gnupg must be controlled by the adversary and the ciphertext should be trusted. Related to a "CWE-20: Improper Input Validation" issue affecting...

I Was Cited in a Court Decision

An article I co-wrote -- my first law journal article -- was cited by the Massachusetts Supreme Judicial Court -- the state supreme court -- in a case on compelled decryption. Here's the first, in footnote 1: We understand the word "password" to be synonymous with other terms that cell phone user...

Multi Gather Ubiquiti UniFi Controller Backup

On an Ubiquiti UniFi controller, reads the system.properties configuration file and downloads the backup and autobackup files. The files are then decrypted using a known encryption key, then attempted to be repaired by zip. Meterpreter must be used due to the large file sizes, which can be flaky ...

MGASA-2019-0106 Updated openssl packages fix security vulnerability

If an application encounters a fatal protocol error and then calls SSLshutdown twice once to send a closenotify, and once to receive one then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received...

MGASA-2019-0103 Updated gnutls packages fix security vulnerability

A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade...

Padding Oracle Attack

openssl is vulnerable to padding oracle attacks. In the event of a fatal protocol error and SSLshutdown is called twice, an attacker is able to perform a padding oracle attack to decrypt data by sending a 0 byte record with invalid padding, causing the application to behave differently due to...

OpenSSL 1.0.2 < 1.0.2r Vulnerability

The version of OpenSSL installed on the remote host is prior to 1.0.2r. It is, therefore, affected by a vulnerability as referenced in the 1.0.2r advisory. - If an application encounters a fatal protocol error and then calls SSLshutdown twice once to send a closenotify, and once to receive one th...
