high Nessus Plugin ID 271606
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。- 已解決 Linux 核心中的下列弱點：s390/crypto: use vector instructions only if available for ChaCha20 Commit 349d03ffd5f6 (crypto: s390 - add crypto library interface for ChaCha20) added a library interface to the s390 specific ChaCha20 implementation. However no check was added to verify if the required facilities are installed before branching into the assembler code. If compiled into the kernel, this will lead to the following crash, if vector instructions are not available:
