The podman packages version podman-1.6.4-32.el79 as released for Red Hat Enterprise Linux 7 Extras via RHSA-2022:2190 (https://access.redhat.com/errata/RHSA-2022:2190) included an incorrect version of podman that was missing multiple bug and security fixes. One of the fixes regressed in that update was the fix for CVE-2020-14370, that was previously corrected in the podman packages in Red Hat Enterprise Linux 7 Extras via RHSA-2020:5056 (https://access.redhat.com/errata/RHSA-2020:5056). The CVE-2022-2739 was assigned to this security regression and it is specific to the podman packages produced by Red Hat.
The original issue - CVE-2020-14370 - could possibly allow an attacker to gain access to sensitive information stored in environment variables. For more details about the original issue, see:

IBM Java Security Components in IBM SDK, Java Technology Edition 8 before SR1 FP10, 7 R1 before SR3 FP10, 7 before SR9 FP10, 6 R1 before SR8 FP7, 6 before SR16 FP7, and 5.0 before SR16 FP13 stores plaintext information in memory dumps, which allows local users to obtain sensitive information by reading a file.
BSD mailx 8.1.2 and earlier allows remote attackers to execute arbitrary commands via a crafted email address.
Use after free in WebBluetooth in Google Chrome prior to 78.0.3904.108 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted HTML page.
An unspecified vulnerability in Java SE related to the Deployment component could allow an unauthenticated attacker to cause low confidentiality impact, low integrity impact, and no availability impact.
A flaw was found in the "Leaf and Chain" OCSP policy implementation in JSS' CryptoManager versions after 4.4.6, 4.5.3, 4.6.0, where it implicitly trusted the root certificate of a certificate chain. Applications using this policy may not properly verify the chain and could be vulnerable to attacks such as Man in the Middle.
It was found that icedtea-web though 1.7.2 and 1.8.2 did not properly sanitize paths from <jar/> elements in JNLP files. An attacker could trick a victim into running a specially crafted application and use this flaw to upload arbitrary files to arbitrary locations in the context of the user.
All builds of Eclipse OpenJ9 prior to 0.15 contain a bug where the loop versioner may fail to privatize a value that is pulled out of the loop by versioning - for example if there is a condition that is moved out of the loop that reads a field we may not privatize the value of that field in the modified copy of the loop allowing the test to see one value of the field and subsequently the loop to see a modified field value without retesting the condition moved out of the loop. This can lead to a variety of different issues but read out of array bounds is one major consequence of these problems.
Adobe Flash Player versions 32.0.0.192 and earlier, 32.0.0.192 and earlier, and 32.0.0.192 and earlier have an use after free vulnerability. Successful exploitation could lead to arbitrary code execution.
A flaw was discovered in fence-agents, prior to version 4.3.4, where using non-ASCII characters in a guest VM's comment or other fields would cause fencerhevm to exit with an exception. In cluster environments, this could lead to preventing automated recovery or otherwise denying service to clusters of which that VM is a member.
Adobe Flash Player versions 32.0.0.171 and earlier, 32.0.0.171 and earlier, and 32.0.0.171 and earlier have a use after free vulnerability. Successful exploitation could lead to arbitrary code execution.
IBM JDK 7 SR10 FP45 (7.0.10.45), 7.1 SR4 FP45 (7.1.4.45), and 8 SR5 FP35 (8.0.5.35) fix a flaw described by upstream as:
Eclipse OpenJ9 is vulnerable to a denial of service, caused by the execution of a method past the end of bytecode array by the Java bytecode verifier. A remote attacker could exploit this vulnerability to cause the application to crash.

An issue was discovered in AdvanceCOMP through 2.1. An invalid memory address occurs in the function advpngunfilter8 in lib/png.c. It can be triggered by sending a crafted file to a binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact when a victim opens a specially crafted file.
A flaw was discovered that may allow an attacker to escape from the flatpak sandbox via /proc/self/exe.

IBM JDK 8 SR5 FP30 (8.0.5.30) and IBM JDK 7R1 SR4 FP40 (7.1.4.40) fix a flaw described by upstream as:
Eclipse OpenJ9 is vulnerable to a buffer overflow, caused by improper bounds checking by the jiosnprintf() and jiovsnprintf() functions. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

IBM JDK 8 SR5 FP30 (8.0.5.30) fixes a flaw described by upstream as:
Eclipse OpenJ9 could allow a remote attacker to execute arbitrary code on the system, caused by the failure to omit a null check on the receiver object of an Unsafe call when accelerating it. An attacker could exploit this vulnerability to execute arbitrary code on the system.

In elfutils 0.175, a negative-sized memcpy is attempted in elfcvtnote in libelf/notexlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash).

An issue was discovered in sd-bus in systemd 239. busprocessobject() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).
A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux (since version v219-62.2) and CentOS. Function dispatchmessagereal() in journald-server.c does not free the memory allocated by setiovecfieldfree() to store the CMDLINE= entry. A local attacker may use this flaw to make systemd-journald crash.
However systemd-journald crash is automatically restarted by systemd by default.
Oracle Java SE 8u201 fixes an unspecified vulnerability in the Deployment component (CVE-2019-2449). Upstream has CVSS scored this issue as: 3.1/CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L

An off-by-one error was found in spice when accessing arrays. A malicious guest user can use this for a host denial of service.
A flaw was found in NFS in the Linux Kernel. An attacker who is able to mount an exported NFS filesystem is able to trigger a null pointer dereference by an invalid NFS sequence.
This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost.
Upstream fix:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=01310bb7c9c98752cc763b36532fab028e0f8f81
A flaw was found in systemd-journald. An out-of-bounds read when parsing a crafted syslog message that could lead to information disclosure.
A flaw was found in systemd-journald. An uncontrolled alloca() by writing a crafted message to /run/systemd/journal/socket that results in a stack buffer overflow. This can lead to a denial of service attack or arbitrary code execution in some cases.
A flaw was found in systemd-journald. A stack buffer overflow when passing several MB of arguments to a program calling syslog function. This can lead to a denial of service attack or arbitrary code execution in some cases.
It was found that RHSA-2018:2918 did not fully fix CVE-2018-16509. An attacker could possibly exploit another variant of the flaw and bypass the -dSAFER protection to, for example, execute arbitrary shell commands via a specially crafted PostScript document. This only affects ghostscript 9.07 as shipped with Red Hat Enterprise Linux 7.
Adobe Security Bulletin APSB18-44 for Adobe Flash Player describes a flaw that can possibly lead to arbitrary code execution when Flash Player is used to play a specially crafted SWF file:

etcd versions 3.2.x before 3.2.26 and 3.3.x before 3.3.11 are vulnerable to an improper authentication issue when role-based access control (RBAC) is used and client-cert-auth is enabled. If an etcd client server TLS certificate contains a Common Name (CN) which matches a valid RBAC username, a remote attacker may authenticate as that user with any valid (trusted) client certificate in a REST API request to the gRPC-gateway.
Object lifecycle issue in Chrome Custom Tab in Google Chrome prior to 65.0.3325.146 allowed a remote attacker to spoof the contents of the Omnibox (URL bar) via a crafted HTML page.
