Stack overflow in GPU Process
CVE: CVE-2021-21153
Component: chromium-browser
CVSS v3: 8.7/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Release date: 2021-02-16T00:00:00+00:00

Stack buffer overflow in GPU Process in Google Chrome on Linux prior to 88.0.4324.182 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page.

Statement: Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery.

Integer overflow in WriteTHUMBNAILImage of coders/thumbnail.c
CVE: CVE-2021-20312
Component: ImageMagick
CWE: CWE-190
Severity: Low
CVSS v3: 5.3/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Release date: 2021-02-25T00:00:00+00:00

A flaw was found in ImageMagick, where an integer overflow in WriteTHUMBNAILImage of coders/thumbnail.c may trigger undefined behavior via a crafted image file that is submitted by an attacker and processed by an application using ImageMagick. The highest threat from this vulnerability is to system availability.

Statement: This flaw is out of support scope for Red Hat Enterprise Linux 6 and 7. It does not affect Red Hat Enterprise Linux 8 because the ImageMagick package is not shipped. To learn more about Red Hat Enterprise Linux support scope, please see https://access.redhat.com/support/policy/updates/errata/ .

Linux kernel eBPF bitwise ops ALU32 bounds tracking
CVE: CVE-2021-3490
Component: kernel
CWE: CWE-119
Severity: Moderate
CVSS v3: 7.9/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Release date: 2021-05-11T00:00:00+00:00

A flaw was found in the Linux kernels eBPF verification code. It was discovered that eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) did not update the 32-bit bounds.  By default accessing the eBPF verifier is only accessible to privileged users with CAP_SYS_ADMIN. A local user with the ability to insert eBPF instructions could use this flaw to crash the system or possibly escalate their privileges on the system.


Remediation:
The default Red Hat Enterprise Linux kernel prevents unprivileged users from being able to use eBPF by the kernel.unprivileged_bpf_disabled sysctl.   This would require a privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw reducing its attack space.

For the Red Hat Enterprise Linux 7 the eBPF for unprivileged users is always disabled.
For the Red Hat Enterprise Linux 8 to confirm the current state, inspect the sysctl with the command:

# cat /proc/sys/kernel/unprivileged_bpf_disabled

The setting of 1 would mean that unprivileged users can not use eBPF, mitigating the flaw.

A kernel update will be required to mitigate the flaw for the root or users with CAP_SYS_ADMIN capabilities.
Heap buffer overflow in PDFium
CVE: CVE-2021-37984
Component: chromium-browser
CVSS v3: 8.7/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Release date: 2021-10-19T00:00:00+00:00

Heap buffer overflow in PDFium in Google Chrome prior to 95.0.4638.54 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

Statement: Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery.

Linux blkback driver may leak persistent grants (XSA 371)
CVE: CVE-2021-28688
Component: xen
CVSS v3: 6.4/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-03-30T00:00:00+00:00

The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values. This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died, leaving around zombie domains. All Linux versions having the fix for XSA-365 applied are vulnerable. XSA-365 was classified to affect versions back to at least 3.11.

Statement: Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery.

net: e1000: infinite loop while processing transmit descriptors
CVE: CVE-2021-20257
Component: QEMU
CWE: CWE-835
Severity: Low
CVSS v3: 2.4/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L
Release date: 2021-02-10T00:00:00+00:00

An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Statement: This issue affects the version of the qemu-kvm package shipped with Red Hat Enterprise Linux 6, 7 and 8. Future qemu-kvm package updates for Red Hat Enterprise Linux 7 and 8 may address this issue.

This issue has been rated as having Low security impact and is not currently planned to be addressed in future updates of Red Hat Enterprise Linux 5 and 6. For additional information, refer

KVM: SVM: out-of-bounds read/write in sev_es_string_io
CVE: CVE-2021-4093
Component: kernel
CWE: CWE-787
Severity: Moderate
CVSS v3: 7.4/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
Release date: 2021-11-22T00:00:00+00:00

A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example, outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario.

Statement: AMD Secure Encrypted Virtualization (SEV) is currently provided as a Technology Preview in RHEL and, therefore, unsupported for production use. For additional details please see https://access.redhat.com/articles/4491591 and https://access.redhat.com/support/offerings/techpreview.

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

usb: chipidea: ci_hdrc_imx: Also search for 'phys' phandle

When passing 'phys' in the devicetree to describe the USB PHY phandle
(which is the recommended way according to
Documentation/devicetree/bindings/usb/ci-hdrc-usb2.txt) the
following NULL pointer dereference is observed on i.MX7 and i.MX8MM:

[    1.489344] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000098

[    1.573973] lr : imx7d_charger_detection+0x22c/0x510

This happens because the charger functions check for the phy presence
inside the imx_usbmisc_data structure (data->usb_phy), but the chipidea
core populates the usb_phy passed via 'phys' inside 'struct ci_hdrc'
(ci->usb_phy) instead.

This causes the NULL pointer dereference inside imx7d_charger_detection().

Fix it by also searching for 'phys' in case 'fsl,usbphy' is not found.

Tested on a imx7s-warp board.

file traversal affecting SVG files
CVE: CVE-2021-41178

CVSS v3: 9.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Release date: 2021-10-25T00:00:00+00:00

Nextcloud is an open-source, self-hosted productivity platform. Prior to versions 20.0.13, 21.0.5, and 22.2.0, a file traversal vulnerability makes an attacker able to download arbitrary SVG images from the host system, including user provided files. This could also be leveraged into a XSS/phishing attack, an attacker could upload a malicious SVG file that mimics the Nextcloud login form and send a specially crafted link to victims. The XSS risk here is mitigated due to the fact that Nextcloud employs a strict Content-Security-Policy disallowing execution of arbitrary JavaScript. It is recommended that the Nextcloud Server be upgraded to 20.0.13, 21.0.5 or 22.2.0. There are no known workarounds aside from upgrading.

A flaw was found in ansible. Credentials, such as secrets, are being disclosed in console log by default and not protected by no_log feature when using those modules. An attacker can take advantage of this information to steal those credentials. The highest threat from this vulnerability is to data confidentiality.

Statement: The version of ansible shipped with Red Hat Gluster Storage (RHGS) 3 includes the vulnerable `network/nxos/nxos_*` modules. However, RHGS 3 no longer maintains its own version of Ansible, prerequisite is to enable ansible repository in order to consume the latest version of ansible which has many bug and security fixes.
