CVE-2021-20305 (GCVE-0-2021-20305)

Vulnerability from – Published: 2021-04-05 21:31 – Updated: 2024-08-03 17:37
VLAI?
Summary
A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an invalid signature, causing an assertion failure or possible validation. The highest threat to this vulnerability is to confidentiality, integrity, as well as system availability.
Severity ?
No CVSS data available.

CVE-2021-20291 (GCVE-0-2021-20291)

Vulnerability from – Published: 2021-04-01 17:49 – Updated: 2024-08-03 17:37
VLAI?
Summary
A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a malicious image, which when downloaded and stored by an application using containers/storage, would then cause a deadlock leading to a Denial of Service (DoS).
Severity ?
No CVSS data available.
