SynopsisThe remote EulerOS Virtualization for ARM 64 host is missing a security update.
DescriptionAccording to the version of the python2-ecdsa package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :
- A flaw was found in python-ecdsa, where it did not correctly verify whether signatures used DER encoding.
Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.(CVE-2019-14859)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected python2-ecdsa package.
