If a SAML token has a cert that's not a part of a chain,

Subject: [PATCH] File descriptor vulnerability in the open-vm-tools
|
||||
vmware-user-suid-wrapperx on Linux
|
||||
|
||||
Moving the privilege drop logic (dropping privilege to the real uid and
|
||||
gid of the process for the vmusr service) from suidWrapper to vmtoolsd code.
|
||||
Now the vmtoolsd is not executed with dropped privileges (started as setuid
|
||||
program) and the dumpable attribute of the process is not reset.
|
||||
The unprivileged user will not have access to the privileged file descriptors
|
||||
in the vmtoolsd vmusr process.
|
||||
Also, setting the FD_CLOEXEC flag for both uinputFd and blockFd preventing
|
||||
the file descriptors being inherited any further from the vmtoolsd.

Subject: [PATCH] Track Linux filesystem id (FSID) for quiesced (frozen)
|
||||
filesystems
|
||||
|
||||
Tracking the filesystem FSID along with each file descriptor (FD)
|
||||
as the ioctl FIFREEZE is done. An EBUSY could be seen because of
|
||||
an attempt to freeze the same superblock more than once depending
|
||||
on the OS configuration (e.g. usage of bind mounts). An EBUSY could
|
||||
also mean another process has locked or frozen that filesystem.
|
||||
|
||||
When an EBUSY is received, the filesyste FSID is checked against the
|
||||
list of filesystems that have already be quiesced. If not previously
|
||||
seen, a warning that the filesystem is controlled by another process
|
||||
is logged and the quiesced snapshot request will be rejected.
