usb: dwc3: gadget: Bail from dwc3_gadget_exit() if dwc-&gt;gadget is NULL
CVE: CVE-2021-47272
Component: kernel
Severity: Low
CVSS v3: 5.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

In the Linux kernel, the following vulnerability has been resolved:

usb: dwc3: gadget: Bail from dwc3_gadget_exit() if dwc->gadget is NULL

There exists a possible scenario in which dwc3_gadget_init() can fail:
during during host -> peripheral mode switch in dwc3_set_mode(), and
a pending gadget driver fails to bind.  Then, if the DRD undergoes
another mode switch from peripheral->host the resulting
dwc3_gadget_exit() will attempt to reference an invalid and dangling
dwc->gadget pointer as well as call dma_free_coherent() on unmapped
DMA pointers.

The exact scenario can be reproduced as follows:
 - Start DWC3 in peripheral mode
 - Configure ConfigFS gadget with FunctionFS instance (or use g_ffs)
 - Run FunctionFS userspace application (open EPs, write descriptors, etc)
 - Bind gadget driver to DWC3's UDC
 - Switch DWC3 to host mode
   => dwc3_gadget_exit() is called. usb_del_gadget() will put the
	ConfigFS driver instance on the gadget_driver_pending_list
 - Stop FunctionFS application (closes the ep files)
 - Switch DWC3 to peripheral mode
   => dwc3_gadget_init() fails as usb_add_gadget() calls
	check_pending_gadget_drivers() and attempts to rebind the UDC
	to the ConfigFS gadget but fails with -19 (-ENODEV) because the
	FFS instance is not in FFS_ACTIVE state (userspace has not
	re-opened and written the descriptors yet, i.e. desc_ready!=0).
 - Switch DWC3 back to host mode
   => dwc3_gadget_exit() is called again, but this time dwc->gadget
	is invalid.

Although it can be argued that userspace should take responsibility
for ensuring that the FunctionFS application be ready prior to
allowing the composite driver bind to the UDC, failure to do so
should not result in a panic from the kernel driver.

Fix this by setting dwc->gadget to NULL in the failure path of
dwc3_gadget_init() and add a check to dwc3_gadget_exit() to bail out
unless the gadget pointer is valid.

Improper permission check permits tokens to change their own permissions
CVE: CVE-2021-32688
Component: nextcloud
CVSS v3: 5.8/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N
Release date: 2021-07-12T00:00:00+00:00

Nextcloud Server is a Nextcloud package that handles data storage. Nextcloud Server supports application specific tokens for authentication purposes. These tokens are supposed to be granted to a specific applications (e.g. DAV sync clients), and can also be configured by the user to not have any filesystem access. Due to a lacking permission check, the tokens were able to change their own permissions in versions prior to 19.0.13, 20.0.11, and 21.0.3. Thus fileystem limited tokens were able to grant themselves access to the filesystem. The issue is patched in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds aside from upgrading.

Component: kernel
CWE: CWE-362
Severity: Moderate
CVSS v3: 7.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Release date: 2021-04-18T09:00:00+00:00

A use-after-free flaw was found in the Linux kernel's SCTP socket functionality that triggers a race condition. This flaw allows a local user to escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Statement: This issue is rated as having a Moderate impact because of the privileges required for running the known reproducer. The required privileges are CAP_BPF and CAP_NET_ADMIN capabilities that are disabled by default in Red Hat Enterprise Linux 7. For Red Hat Enterprise Linux 8, the SCTP protocol itself is disabled by default and cannot be used by a user without enablement by an administrator.

Release date: 2021-10-11T00:00:00+00:00

A flaw was found in the HashiCorp vault. Affected versions may have an unexpected interaction between glob-related policies and the Google Cloud secrets engine. In some situations, users may have more privileges than intended.

Statement: This vulnerability is related to the Vault’s Google Cloud secrets engine documentation update. The Vault operators using the Google Cloud secrets engine should review their Vault policies to ensure they meet their requirements and adhere to the principle of least privilege. More can be found in the official HashiCorp article for this vulnerability:

SVN authz protected copyfrom paths regression

A flaw was found in Subversion. When using path-based authorization (authz), the helper function detect_changed() does not omit potentially sensitive information from log messages. In particular, if a node is copied from a protected location, its 'copyfrom' path (the path to the protected location) is reported even when omission should occur.

There is a comment in qdisc_create() about us not calling ops->reset()

err_out4:
	/*
	 * Any broken qdiscs that would require a ops->reset() here?
	 * The qdisc was never in action so it shouldn't be necessary.

As taprio sets a timer before actually receiving a packet, we need
to cancel it from ops->destroy, just in case ops->reset has not
been called.

Component: Foxit PDF Reader JPG2000 File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
Release date: 2021-10-15T12:36:26.307000+00:00

Foxit PDF Reader JPG2000 File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of PDF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-14812.
