X41 discovered a vulnerability in Chilkat's ASN.1 decoder

X41 discovered multiple vulnerabilities in Antragsgrün

The Chilkat library generated secret key material using a pseudorandom number generator not designed for cryptographic purposes. Attackers observing a sufficient number of outputs can recover past and future outputs of it. This includes, for example, key material generated with it, allowing attackers to decrypt or alter data protected by the key material.

As part of his master thesis Leonard Rapp analyzed the security of various popular unikernels. This blogpost is the last one in the unikernel series. It discusses some of the findings and draws a conclusion.

Several security weaknesses and missing mitigations were discovered in various unikernel systems

The research unikernel RustHermit was further audited for security vulnerabilities and effectiveness of its mitigations.

CVE-2021-34600: How predictable random numbers (literally) open the door for attackers: Our discovery of a flaw in the generation of AES keys, used for both physical and remote access, in a popular alarm system's parameterization software. Includes a proof-of-concept for cloning NFC tags!

The compasX parameterization software for complex alarm systems generated the AES keys used for both physical access control (via NFC tags) and remote management in an insecure fashion.

The research unikernel RustyHermit lacks of several memory protection mechanisms which significantly ease attacks on vulnerable applications
