CVE-2018-1302

httpd: Use-after-free on HTTP/2 stream shutdown

When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk.

CVE-2018-1301

httpd: Out of bounds access after failure in reading the HTTP request

A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.

CVE-2018-1283

httpd: Improper handling of headers in mod_session can allow a remote user to modify session data for CGI applications

In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications.

samba: Weak authentication protocol regression

A flaw was found in the way samba before 4.7.9 and 4.8.4 allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled. A man-in-the-middle attacker could use this flaw to read the credential and other details passed between the samba server and client.

tendrl-api: Improper cleanup of session token can allow attackers to hijack user sessions

Tendrl API in Red Hat Gluster Storage before 3.4.0 does not immediately remove session tokens after a user logs out. Session tokens remain active for a few minutes allowing attackers to replay tokens acquired via sniffing/MITM attacks and authenticate as the target user.

CVE-2018-17199

httpd: mod_session_cookie does not respect expiry time

In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded.
