ALAS2-2019-1189


Amazon Linux 2 Security Advisory: ALAS-2019-1189
Advisory Release Date: 2019-05-20 18:05 Pacific
Severity: Important

Issue Overview:

In Apache HTTP Server with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. (CVE-2019-0211 )

mod_http2: read-after-free on a string compare (CVE-2019-0196 )

mod_http2: possible crash on late upgrade (CVE-2019-0197 )

httpd: URL normalization inconsistency (CVE-2019-0220 )

In Apache HTTP Server 2.4 releases 2.4.37 and 2.4.38, a bug in mod_ssl when using per-location client certificate verification with TLSv1.3 allowed a client to bypass configured access control restrictions.(CVE-2019-0215 )

A race condition was found in mod_auth_digest when the web server was running in a threaded MPM configuration. It could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions.(CVE-2019-0217 )
