CVE-2021-43565

Опубликовано: 02 дек. 2021
Источник: redhat
CVSS3: 7.5
EPSS Низкий

Описание

The x/crypto/ssh package before 0.0.0-20211202192323-5770296d904e of golang.org/x/crypto allows an attacker to panic an SSH server.

There's an input validation flaw in golang.org/x/crypto's readCipherPacket() function. An unauthenticated attacker who sends an empty plaintext packet to a program linked with golang.org/x/crypto/ssh could cause a panic, potentially leading to denial of service.

Отчет

go-toolset shipped with Red Hat Developer Tools - Compilers and golang shipped with Red Hat Enterprise Linux 8 are not affected by this flaw because they do not ship the vulnerable code. This flaw was rated to have a Moderate impact because it is not shipped in the Golang standard library and thus has a reduced impact to products compared with other flaws of this type.
