CVE-2019-6486 Denial of service affecting P-521 and P-384 curves in crypto/elliptic
Denial of service affecting P-521 and P-384 curves in crypto/elliptic
A DoS vulnerability in the crypto/elliptic implementations of the P-521 and P-384 elliptic curves may let an attacker craft inputs that consume excessive amounts of CPU.
These inputs might be delivered via TLS handshakes, X.509 certificates, JWT tokens, ECDH shares or ECDSA signatures. In some cases, if an ECDH private key is reused more than once, the attack can also lead to key recovery.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will

CVE-2019-6486 golang: crypto/elliptic implementations of P-521 and P-384 elliptic curves allow for denial of service
Go before versions 1.10.8 and 1.11.5 has a vulnerability in the crypto/elliptic implementations of the P-521 and P-384 elliptic curves. A remote attacker can exploit this by crafting inputs that consume excessive amounts of CPU. These inputs might be delivered via TLS handshakes, X.509 certificates, JWT tokens, ECDH shares or ECDSA signatures. In some cases, if an ECDH private key is reused more than once, the attack can also lead to key recovery.
