flow: Avoid unsafe comparison of minimasks.

The following, run inside the OVS sandbox, caused OVS to abort when
Address Sanitizer was used:

    ovs-vsctl add-br br-int

This fixes the problem, which although largely theoretical could crop up
with odd implementations of memcmp(), perhaps ones optimized in various
"clever" ways.  All in all, it seems best to avoid the theoretical problem.

FROM THE EDITOR

**Securing your edge infrastructure**

Edge security is becoming increasingly important as more organizations turn to edge computing to benefit from the flexibility of hybrid cloud computing and deliver faster, more reliable services at a lower cost.

When we surveyed IT decision makers in 2021 for our 2022 Global Tech Outlook report about what emerging technologies they were most likely to consider using in the next year, or are currently using, 28% said edge computing (up from 25% in 2020). Furthermore, a July 2022 report from 451 Research reveals that "large organizations will significantly expand edge computing infrastructure in two years."1

In edge computing, an increase in data and processing outside the traditional datacenter creates potential risk to organizations. Reduced physical security, a limited compute footprint, lower cost expectations and remote management are often compounded by a lack of IT personnel. These issues combine to create relaxed standards for security and policy and expand the attack surface.

However, there are ways edge resources can improve security. For example, IDC says "63% of organizations report using edge resources to enhance cybersecurity through monitoring networks." IDC also says "replicating data \[using edge resources\] across multiple locations" can "reduce \[the\] impact of ransomware attacks."2

Red Hat provides trusted open source software that helps organizations implement a layered security approach across infrastructure, the application stack and the life cycle for better security on site, in cloud environments or at edge sites.

In this issue of Red Hat Shares, learn about security considerations for edge implementations, key edge security issues for CIOs, how Red Hat helped a customer reduce its edge deployment time while enhancing its infrastructure security and more. Plus, just for fun, we threw in a video from our "In the Clouds" series about how edge computing is being used to solve problems on the International Space Station.

Source: https://github.com/COVESA/dlt-daemon

Business recommendation:  
------------------------  
The project fixed the vulnerability with commit 855e0017a980d2990c16f7dbf3b4983b48fac272  
(https://github.com/COVESA/dlt-daemon/commit/855e0017a980d2990c16f7dbf3b4983b48fac272).

No new version has been tagged, thus an update to the current master branch is recommended.

Vulnerability overview/description:  
-----------------------------------  
1) Null-Pointer Dereference (CVE-2022-39837)  
Due to a faulty DLT file parser, a malicious DLT file that crashes the process  
can be created. This is due to missing validation checks.

2) Heap Buffer Over-Read (CVE-2022-39836)  
The DLT file parser will over read one byte from heap memory when converting  
a malicious DLT file.

Proof of concept:  
-----------------  
1) Null-Pointer Dereference (CVE-2022-39837)  
The following example DLT file will cause a null pointer dereference and crash the  
dlt-convert process.  
However, the crash is caused in /dlt-daemon/src/shared/dlt_common.c:714 and  
thus will most likely affect the whole dlt-daemon suite.

xxd nullpointer_dereference.dlt  
00000000: 444c 5401 ffff ffff 0000 0000 4141 4141  DLT.........AAAA  
00000010: ffff ffff                                ....

Running the file causes the following crash:

./dlt-convert -m nullpointer_dereference.dlt  
[ 7118.461371]~DLT~10310~WARNING  ~Cannot read standard header extra parameters  
from file!  
[1]    10310 segmentation fault (core dumped)  
./dlt-convert -m nullpointer_dereference.dlt

The error occurs as the htypew field in the DltStandardHeader indicates that  
a DltExtendedHeader is supplied. However, it is never checked, if an extended  
header is actually supplied within the DLT file.

2) Heap Buffer Over-Read (CVE-2022-39836)  
The following example DLT file will cause a heap buffer over-read by one byte if  
executed with ./dlt-convert -m <malicious_dlt_file>

Red Hat Security Advisory 2022-6701-01

Ubuntu Security Notice 5640-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux kernel's Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use this to cause a denial of service.

==========================================================================  
Ubuntu Security Notice USN-5640-1  
September 26, 2022

linux-oracle vulnerabilities  
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:  
- linux-oracle: Linux kernel for Oracle Cloud systems

Details:

It was discovered that the framebuffer driver on the Linux kernel did not  
verify size limits when changing font or screen size, leading to an out-of-  
bounds write. A local attacker could use this to cause a denial of service  
(system crash) or possibly execute arbitrary code. (CVE-2021-33655)

Duoming Zhou discovered that race conditions existed in the timer handling  
implementation of the Linux kernel's Rose X.25 protocol layer, resulting in  
use-after-free vulnerabilities. A local attacker could use this to cause a  
denial of service (system crash). (CVE-2022-2318)

Roger Pau Monné discovered that the Xen virtual block driver in the Linux  
kernel did not properly initialize memory pages to be used for shared  
communication with the backend. A local attacker could use this to expose  
sensitive information (guest kernel memory). (CVE-2022-26365)

Roger Pau Monné discovered that the Xen paravirtualization frontend in the  
Linux kernel did not properly initialize memory pages to be used for shared  
communication with the backend. A local attacker could use this to expose  
sensitive information (guest kernel memory). (CVE-2022-33740)

It was discovered that the Xen paravirtualization frontend in the Linux  
kernel incorrectly shared unrelated data when communicating with certain  
backends. A local attacker could use this to cause a denial of service  
(guest crash) or expose sensitive information (guest kernel memory).  
(CVE-2022-33741, CVE-2022-33742)

Jan Beulich discovered that the Xen network device frontend driver in the  
Linux kernel incorrectly handled socket buffers (skb) references when  
communicating with certain backends. A local attacker could use this to  
cause a denial of service (guest crash). (CVE-2022-33743)

Oleksandr Tyshchenko discovered that the Xen paravirtualization platform in  
the Linux kernel on ARM platforms contained a race condition in certain  
situations. An attacker in a guest VM could use this to cause a denial of  
service in the host OS. (CVE-2022-33744)

It was discovered that the virtio RPMSG bus driver in the Linux kernel  
contained a double-free vulnerability in certain error conditions. A local  
attacker could possibly use this to cause a denial of service (system  
crash). (CVE-2022-34494, CVE-2022-34495)

Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter  
subsystem in the Linux kernel did not properly handle rules that truncated  
packets below the packet header size. When such rules are in place, a  
remote attacker could possibly use this to cause a denial of service  
(system crash). (CVE-2022-36946)

Update instructions:

The problem can be corrected by updating your system to the following  
package versions:

Ubuntu 22.04 LTS:  
   linux-image-5.15.0-1018-oracle  5.15.0-1018.23  
   linux-image-oracle              5.15.0.1018.16

After a standard system update you need to reboot your computer to make  
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have  
been given a new version number, which requires you to recompile and  
reinstall all third party kernel modules you might have installed.  
Unless you manually uninstalled the standard kernel metapackages  
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,  
linux-powerpc), a standard system upgrade will automatically perform  
this as well.
