CVE-2020-12607

An issue was discovered in fastecdsa before 2.1.2. When using the NIST P-256 curve in the ECDSA implementation, the point at infinity is mishandled. This means that for an extreme value in k and s^-1, the signature verification fails even if the signature is correct. This behavior is not solely a...

CVE-2020-12607

CVE-2020-12607 affects the fastecdsa library prior to 2.1.2, where using the NIST P-256 curve in the ECDSA implementation mishandles the point at infinity during signature verification. This can cause verification to fail for an otherwise valid signature when extreme values occur for k and s^-1, ...

Securing Internet Videoconferencing Apps: Zoom and Others

The NSA just published a survey of video conferencing apps. So did Mozilla. Zoom is on the good list, with some caveats. The company has done a lot of work addressing previous security concerns. It still has a bit to go on end-to-end encryption. Matthew Green looked at this. Zoom does offer...

Unpatchable 'Starbleed' Bug in FPGA Chips Exposes Critical Devices to Hackers

A newly discovered unpatchable hardware vulnerability in Xilinx programmable logic products could allow an attacker to break bitstream encryption, and clone intellectual property, change the functionality, and even implant hardware Trojans. The details of the attacks against Xilinx 7-Series and...

Zoom Client Encryption Issue Vulnerability

Zoom Client is a video conferencing client application from Zoom USA that supports multiple platforms. An encryption issue vulnerability exists in Zoom Client for Meetings version 4.6.11, which stems from the airhost.exe file using 3423423432325249 as the initialization vector IV for AES-256 CBC...

CVE-2020-11877
