This -assumption is incorrect, and can lead to aliasing violations for some -programs. Maintain the IAKERB context structure after context -establishment and add new IAKERB entry points to refer to it with that -type. Add initiate and established flags to the IAKERB context -structure for use in gss_inquire_context() prior to context -establishment. - -CVE-2015-2696: - -In MIT krb5 1.9 and later, applications which call -gss_inquire_context() on a partially-established IAKERB context can -cause the GSS-API library to read from a pointer using the wrong type, -generally causing a process crash. Java server applications using the -native JGSS provider are vulnerable to this bug. A carefully crafted -IAKERB packet might allow the gss_inquire_context() call to succeed -with attacker-determined results, but applications should not make -access control decisions based on gss_inquire_context() results prior -to context establishment. - - CVSSv2 Vector: AV:N/AC:M/Au:N/C:N/I:N/A:C/E:POC/RL:OF/RC:C - -[ghudson@mit.edu: several bugfixes, style changes, and edge-case -behavior changes;
