## Source: ghsa-malware (2766aea53528ed77bd814610cca5ea5fc97d488f1363648b0661dbfe77280748)
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

The System Security Services Daemon (SSSD) service provides a set of daemons to manage access to remote directories and authentication mechanisms. It also provides the Name Service Switch (NSS) and the Pluggable Authentication Modules (PAM) interfaces toward the system, and a pluggable back-end system to connect to multiple different account sources.
Security Fix(es):
* sssd: out-of-bounds read in the sssd (CVE-2026-6245)
Bug Fix(es) and Enhancement(s):
* Performance impact with enumerate in SSSD > 2.7.3 [rhel-9] (JIRA:RHEL-143416)
* Poor performance of `BE_REQ_INITGROUPS` handling by 'sssd_be' (LDAP RFC2307, no nested groups) [rhel-9] (JIRA:RHEL-150439)
* [RFE] SSSD PAM: Support Microsoft AD PKINIT authentication indicator (ms-pkca) for pam_gssapi_indicators_map [rhel-9] (JIRA:RHEL-152067)

* SSSD Rebase for RHEL 9.9 (JIRA:RHEL-173741)
* [RHEL9.9] Man page update: man sssd_krb5_localauth_plugin ? Missing disable = an2ln (JIRA:RHEL-173742)
* [RHEL9.9] Concurrent child processes trigger unnecessarily backtrace (JIRA:RHEL-173743)
* [RHEL9.9] Detect foreign security principals in AD group members and silently ignore them (JIRA:RHEL-173744)

The proxy-cache and proxy-cache-advanced plugins in Kong Gateway Enterprise and Kong AI Gateway do not escape separator characters when building the cache key, allowing a remote attacker to cause a response cached for one request to be served for a different request on the same Route.
The request-callout plugin in Kong Gateway Enterprise and Kong AI Gateway omits callout headers not sent by the client from its cache key, allowing a cached callout response for a caller to be served to another.
Expected behavior violation in AMD Secure Encrypted Virtualization (SEV) firmware could allow a malicious hypervisor to bypass Reverse Map Table (RMP) protections, potentially resulting in a loss of Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP) guest memory integrity.
Improper validation of unsafe equivalence in input could allow an attacker with high privileges to reclaim the ring buffer queue status page, potentially resulting in loss of guest memory integrity.
Improper validation of Reverse Map Table (RMP) entries in the Secure Encrypted Virtualization (SEV) firmware could allow a privileged attacker to trigger concurrent modifications to RMP entries without proper synchronization potentially resulting in loss of data integrity.
A time-of-check to time-of-use (TOCTOU) race condition in the AMD SEV Secure Encrypted Virtualization (SEV) firmware could allow an attacker with administrative privileges to bypass security checks on scatter lists, potentially resulting in loss of guest integrity.
