4Subject: [PATCH] Preserve GSS context on init/accept failure
5
6After gss_init_sec_context() or gss_accept_sec_context() has created a
7context, don't delete the mechglue context on failures from subsequent
8calls, even if the mechanism deletes the mech-specific context (which
9is allowed by RFC 2744 but not preferred). Check for union contexts
10with no mechanism context in each GSS function which accepts a
11gss_ctx_id_t.
12
13CVE-2017-11462:
14
15RFC 2744 permits a GSS-API implementation to delete an existing
16security context on a second or subsequent call to
17gss_init_sec_context() or gss_accept_sec_context() if the call results
18in an error. This API behavior has been found to be dangerous,
19leading to the possibility of memory errors in some callers. For
20safety, GSS-API implementations should instead preserve existing
21security contexts on error until the caller deletes them.
22
23All versions of MIT krb5 prior to this change may delete acceptor
24contexts on error. Versions 1.13.4 through 1.13.7, 1.14.1 through
251.14.5, and 1.15 through 1.15.1 may also delete initiator contexts on
26error.

10Subject: [PATCH] Prevent KDC unset status assertion failures
11
12Assign status values if S4U2Self padata fails to decode, if an
13S4U2Proxy request uses invalid KDC options, or if an S4U2Proxy request
14uses an evidence ticket which does not match the canonicalized request
15server principal name. Reported by Samuel Cabrero.
16
17If a status value is not assigned during KDC processing, default to
18"UNKNOWN_REASON" rather than failing an assertion. This change will
19prevent future denial of service bugs due to similar mistakes, and
20will allow us to omit assigning status values for unlikely errors such
21as small memory allocation failures.
22
23CVE-2017-11368:
24
25In MIT krb5 1.7 and later, an authenticated attacker can cause an
26assertion failure in krb5kdc by sending an invalid S4U2Self or
27S4U2Proxy request.
