Amazon Linux 2 Security Advisory: ALAS-2019-1341
Advisory Release Date: 2019-10-28 17:42 Pacific
Advisory Updated Date: 2019-10-30 21:07 Pacific
Severity: Medium
Issue Overview:

A cross-site scripting vulnerability was found in Apache httpd, affecting the mod_proxy error page. Under certain circumstances, a crafted link could inject content into the HTML displayed in the error page, potentially leading to client-side exploitation.(CVE-2019-10092)

A vulnerability was discovered in Apache httpd, in mod_remoteip. A trusted proxy using the "PROXY" protocol could send specially crafted headers that can cause httpd to experience a stack buffer overflow or NULL pointer dereference, leading to a crash or other potential consequences.\n\nThis issue could only be exploited by configured trusted intermediate proxy servers. HTTP clients such as browsers could not exploit the vulnerability.(CVE-2019-10097)

A vulnerability was discovered in Apache httpd, in mod_rewrite. Certain self-referential mod_rewrite rules could be fooled by encoded newlines, causing them to redirect to an unexpected location. An attacker could abuse this flaw in a phishing attack or as part of a client-side attack on browsers.(CVE-2019-10098)
