CVE-2026-90462 [MEDIUM] CWE-280 CVE-2026-90462: A flaw was found in SSSD. When configured with the LDAP access provider and `ldap_access_order` incl A flaw was found in SSSD. When configured with the LDAP access provider and `ldap_access_order` including `ppolicy` or `lockout`, a fail-open condition in the LDAP ppolicy access check can occur if a user lookup returns zero results. This can incorrectly return success and cache an allow decision, permitting continued authorization for a deleted or

CVE-2018-13988 [MEDIUM] CWE-125 CVE-2018-13988: Poppler through 0.62 contains an out of bounds read vulnerability due to an incorrect memory access Poppler through 0.62 contains an out of bounds read vulnerability due to an incorrect memory access that is not mapped in its memory space, as demonstrated by pdfunite. This can result in memory corruption and denial of service. This may be exploitable when a victim opens a specially crafted PDF file.

CVE-2026-68743 [HIGH] CWE-125 CVE-2026-68743: A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate t A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket, causing an out-of-bounds read and process crash, resulting in a denial of se

CVE-2021-20291 [MEDIUM] CWE-667 CVE-2021-20291: A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. Whe A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which neve

CVE-2019-19353 [HIGH] CWE-266 CVE-2019-19353: An insecure modification vulnerability in the /etc/passwd file was found in the operator-framework/h An insecure modification vulnerability in the /etc/passwd file was found in the operator-framework/hive as shipped in Red Hat Openshift 4. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges.

CVE-2019-19352 [HIGH] CWE-266 CVE-2019-19352: An insecure modification vulnerability in the /etc/passwd file was found in the operator-framework/p An insecure modification vulnerability in the /etc/passwd file was found in the operator-framework/presto as shipped in Red Hat Openshift 4. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges.

CVE-2020-14336 [MEDIUM] CWE-770 CVE-2020-14336: A flaw was found in the Restricted Security Context Constraints (SCC), where it allows pods to craft A flaw was found in the Restricted Security Context Constraints (SCC), where it allows pods to craft custom network packets. This flaw allows an attacker to cause a denial of service attack on an OpenShift Container Platform cluster if they can deploy pods. The highest threat from this vulnerability is to system availability.

CVE-2020-15706 [MEDIUM] CWE-362 CVE-2020-15706: GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnera GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions.

CVE-2019-10150 [MEDIUM] CWE-287 CVE-2019-10150: It was found that OpenShift Container Platform versions 3.6.x - 4.6.0 does not perform SSH Host Key It was found that OpenShift Container Platform versions 3.6.x - 4.6.0 does not perform SSH Host Key checking when using ssh key authentication during builds. An attacker, with the ability to redirect network traffic, could use this to alter the resulting build output.

CVE-2023-0264 [MEDIUM] CWE-287 CVE-2023-0264: A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate requests. An authenticated attacker who could obtain information from a user request within the same realm could use that data to impersonate the victim and generate new session tokens.
