memory disclosure in certain queries
CVE: CVE-2021-3677
Component: postgresql
CWE: CWE-200
Severity: Moderate
CVSS v3: 6.7/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Release date: 2021-08-12T00:00:00+00:00

A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting.

Buffer Overflow vulnerability in authfile.c
CVE: CVE-2021-37519
Component: memcached
CWE: CWE-119
Severity: Low
CVSS v3: 4.6/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

A flaw was found in memcached, where it is vulnerable to a denial of service caused by a heap-based buffer overflow in the authfile.c script. By persuading a victim to open a specially-crafted file, an attacker can cause a denial of service.


Remediation:
DoS due to FPE in Exiv2::Internal::resolveLens0xffff
CVE: CVE-2021-34335
Component: exiv2
CWE: CWE-369
Severity: Low
CVSS v3: 4.6/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H
Release date: 2021-08-08T00:00:00+00:00

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A floating point exception (FPE) due to an integer divide by zero was found in Exiv2 versions v0.27.4 and earlier. The FPE is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p t` or `-P t`). The bug is fixed in version v0.27.5.


Remediation:
Heap out-of-bounds write due to miscalculation of space required for quoting
CVE: CVE-2021-20233
Component: grub2
CWE: CWE-787
Severity: Moderate
CVSS v3: 7.0/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H
Release date: 2021-03-02T18:00:00+00:00

A flaw was found in grub2. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw in the Linux kernel allows a privileged BPF program to obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel in the eBPF subsystem


Remediation:
The default Red Hat Enterprise Linux kernel setting prevents unprivileged users from being able to use eBPF via the kernel.unprivileged_bpf_disabled sysctl. As such, exploiting this issue would require a privileged user with CAP_SYS_ADMIN or root.

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 (default) would mean that unprivileged users cannot use eBPF. Otherwise, to disable eBPF for unprivileged users, add:

kernel.unprivileged_bpf_disabled = 1

To the file "/etc/sysctl.d/disable-ebpf.conf"

Then running the following command as root:

# sudo sysctl --system

If a math string was passed through as user provided data to the math function, external users could run arbitrary PHP code by crafting a malicious math string. Users should upgrade to version 3.1.42 or 4.0.2 to receive a patch.
