Cisco IOS XE Data Forgery Issue Vulnerability (CNVD-2020-31991)
Cisco IOS XE is the United States Cisco Cisco company's set of operating system developed for its network equipment. A data forgery vulnerability exists in software image validation in Cisco IOS XE, which arises from a program not properly checking the code area used to manage the digital signatu...
CVE-2020-3209
A vulnerability in software image verification in Cisco IOS XE Software could allow an unauthenticated, physical attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability is due to an improper check on the area of code that manag...
Improper Signature Verification
fastecdsa does not properly perform signature verification. When Elliptic Curve Digital Signature Algorithm ECDSA signature is used with NIST P-256 SHA-256, it does not properly handled the point at infinity, leading to a failure in the signature verification if an extreme value in k and s^-1 is...
fastecdsa data forgery issue vulnerability
fastecdsa is a Python library for fast elliptic curve encryption by AntonKueltz Software Developers. A security vulnerability exists in fastecdsa versions prior to 2.1.2. An attacker can exploit the vulnerability to benefit by successfully guessing the user whose signature verification will fail...
PT-2020-2875
Name of the Vulnerable Software and Affected Versions Cisco IOS XE Software affected versions not specified Description The issue is related to insufficient validation of a user-supplied open virtual appliance OVA during installation, which could allow an authenticated, local attacker to gain...
PT-2020-2693
Name of the Vulnerable Software and Affected Versions Cisco IOS XE Software affected versions not specified Description The issue is related to errors in cryptographic signature verification during the initial boot process of system image files. This could allow an unauthenticated, physical...
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...
