漏洞描述

Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.

修复方式

sudo apt update && sudo apt dist-upgrade

漏洞判定

执行命令apt policy PackageName获取软件包版本号，版本小于修复版本，则受此漏洞影响，版本大于等于修复版本，则此漏洞已修复
