Rejected reason: CVE-2023-39190 was found to be a duplicate of CVE-2023-31436. Please see https://access.redhat.com/security/cve/CVE-2023-31436 for information about affected products and security errata.

It was discovered that the update for the virt:rhel module in the RHSA-2020:4676 (https://access.redhat.com/errata/RHSA-2020:4676) erratum released as part of Red Hat Enterprise Linux 8.3 failed to include the fix for the qemu-kvm component issue CVE-2020-10756, which was previously corrected in virt:rhel/qemu-kvm via erratum RHSA-2020:4059 (https://access.redhat.com/errata/RHSA-2020:4059). CVE-2021-20295 was assigned to that Red Hat specific security regression. For more details about the original security issue CVE-2020-10756, refer to bug 1835986 or the CVE page: https://access.redhat.com/security/cve/CVE-2020-10756.

A flaw was found in jboss-remoting in versions before 5.0.20.SP1-redhat-00001. A malicious attacker could cause threads to hold up forever in the EJB server by writing a sequence of bytes corresponding to the expected messages of a successful EJB client request, but omitting the ACK messages, or just tamper with jboss-remoting code, deleting the lines that send the ACK message from the EJB client code resulting in a denial of service. The highest threat from this vulnerability is to system availability.

An insecure modification flaw in the /etc/passwd file was found in the redhat-sso-7 container. An attacker with access to the container can use this flaw to modify the /etc/passwd and escalate their privileges.

redhat-certification 7 does not properly restrict the number of recursive definitions of entities in XML documents, allowing an unauthenticated user to run a "Billion Laugh Attack" by replying to XMLRPC methods when getting the status of an host.

redhat

Files are accessible without restrictions from the /update/results page of redhat-certification 7 package, allowing an attacker to remove any file accessible by the apached user.

redhat

It was discovered that the /configuration view of redhat-certification 7 does not perform an authorization check and it allows an unauthenticated user to remove a "system" file, that is an xml file with host related information, not belonging to him.

redhat

It was discovered that the /configuration view of redhat-certification 7 does not perform an authorization check and it allows an unauthenticated user to call a "restart" RPC method on any host accessible by the system, even if not belonging to him.

redhat

It was discovered that redhat-certification 7 is not properly configured and it lists all files and directories in the /var/www/rhcert/store/transfer directory, through the /rhcert-transfer URL. An unauthorized attacker may use this flaw to gather sensible information.

redhat

It has been discovered in redhat-certification that any unauthorized user may download any file under /var/www/rhcert, provided they know its name. Red Hat Certification 6 and 7 is vulnerable to this issue.

A flaw was found in all supported versions before wildfly-elytron-1.6.8.Final-redhat-00001, where the WildFlySecurityManager checks were bypassed when using custom security managers, resulting in an improper authorization. This flaw leads to information exposure by unauthenticated access to secure resources.

A flaw was found in JBossWeb in versions before 7.5.31.Final-redhat-3. The fix for CVE-2020-13935 was incomplete in JBossWeb, leaving it vulnerable to a denial of service attack when sending multiple requests with invalid payload length in a WebSocket frame. The highest threat from this vulnerability is to system availability.

The docker packages version docker-1.13.1-108.git4ef4b30.el7 as released for Red Hat Enterprise Linux 7 Extras via RHBA-2020:0053 (https://access.redhat.com/errata/RHBA-2020:0053) included an incorrect version of runc that was missing multiple bug and security fixes. One of the fixes regressed in that update was the fix for CVE-2016-9962, that was previously corrected in the docker packages in Red Hat Enterprise Linux 7 Extras via RHSA-2017:0116 (https://access.redhat.com/errata/RHSA-2017:0116). The CVE-2020-14300 was assigned to this security regression and it is specific to the docker packages produced by Red Hat. The original issue - CVE-2016-9962 - could possibly allow a process inside container to compromise a process entering container namespace and execute arbitrary code outside of the container. This could lead to compromise of the container host or other containers running on the same container host. This issue only affects a single version of Docker, 1.13.1-108.git4ef4b30, shipped in Red Hat Enterprise Linux 7. Both earlier and later versions are not affected.

vg_lookup in daemons/lvmetad/lvmetad-core.c in LVM2 2.02 mismanages memory, leading to an lvmetad memory leak, as demonstrated by running pvs. NOTE: RedHat disputes CVE-2020-8991 as not being a vulnerability since there’s no apparent route to either privilege escalation or to denial of service through the bug

Insecure temporary file vulnerability in RedHat vsdm 4.9.6.

While backporting a feature for a newer branch of BIND9, RedHat introduced a path leading to an assertion failure in buffer.c:420. Affects RedHat versions bind-9.9.4-65.el7 -> bind-9.9.4-72.el7. No ISC releases are affected. Other packages from other distributions who made the same error may also be affected.

It was found that the fix for CVE-2014-0114 had been reverted in JBoss Operations Network 3 (JON). This flaw allows attackers to manipulate ClassLoader properties on a vulnerable server. Exploits that have been published rely on ClassLoader properties that are exposed such as those in JON 3. Additional information can be found in the Red Hat Knowledgebase article: https://access.redhat.com/site/solutions/869353. Note that while multiple products released patches for the original CVE-2014-0114 flaw, the reversion described by this CVE-2019-3834 flaw only occurred in JON 3.

An issue was discovered in Artifex Ghostscript before 9.24. The .setdistillerkeys PostScript command is accepted even though it is not intended for use during document processing (e.g., after the startup phase). This leads to memory corruption, allowing remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact. Note: A reputable source believes that the CVE is potentially a duplicate of CVE-2018-15910 as explained in Red Hat bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=1626193)

An uncontrolled resource consumption flaw has been discovered in redhat-certification in the way documents are loaded. A remote attacker may provide an existing but invalid XML file which would be opened and never closed, possibly producing a Denial of Service.

It was found that subscription-manager's DBus interface before 1.19.4 let unprivileged user access the com.redhat.RHSM1.Facts.GetFacts and com.redhat.RHSM1.Config.Set methods. An unprivileged local attacker could use these methods to gain access to private information, or launch a privilege escalation attack.
