* dix: integer overflow in GetHosts() [CVE-2014-8092 2/4]Alan Coopersmith2015-02-141-0/+6
| | | | | | | | | | | | | | | | | | | | GetHosts() iterates over all the hosts it has in memory, and copies them to a buffer. The buffer length is calculated by iterating over all the hosts and adding up all of their combined length. There is a potential integer overflow, if there are lots and lots of hosts (with a combined length of > ~4 gig). This should be possible by repeatedly calling ProcChangeHosts() on 64bit machines with enough memory. This patch caps the list at 1mb, because multi-megabyte hostname lists for X access control are insane. v2: backport to nx-libs 3.6.x (Mike DePaulo) Reported-by: Ilja Van Sprundel <ivansprundel@ioactive.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Conflicts: os/access.c
* unchecked malloc may allow unauthed client to crash Xserver [CVE-2014-8091]Alan Coopersmith2015-02-141-0/+4
| | | | | | | | | | | | | | | | | | authdes_ezdecode() calls malloc() using a length provided by the connection handshake sent by a newly connected client in order to authenticate to the server, so should be treated as untrusted. It didn't check if malloc() failed before writing to the newly allocated buffer, so could lead to a server crash if the server fails to allocate memory (up to UINT16_MAX bytes, since the len field is a CARD16 in the X protocol).

| | | | | | | | | | (999_nxagent_unbrand-nxagent-brand-x2goagent.full.patch). When launched with NX Agent flavour, the startup screen gets unbranded by this patch (the !M logo does not get shown). When launched with X2Go Agent flavour, the startup screen gets branded with the X2GO logo.

The Fedora review of NX (redistributed) caught the following rpmlint issue: This executable is calling setuid and setgid without setgroups or initgroups. There is a high probability this mean it didn't relinquish all groups, and this would be a potential security issue to be fixed. Seek POS36-C on the web for details about the problem. Ref POS36-C: https://www.securecoding.cert.org/confluence/display/seccode/POS36-C.+Observe+correct+revocation+order+while+relinquishing+privileges This patch adds initgroups() calls to the code to initialize the supplemental group list.
