The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:49842 advisory.

    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: sssd: sudo LDAP provider searches entire directory tree for sudoRole objects by default, enabling     privilege escalation (CVE-2026-14474)

    * sssd: sssd: GPO cache path traversal via unsanitized gPCFileSysPath allows Kerberos authentication     bypass (CVE-2026-14476)

According to the versions of the sssd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function     does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO     management access to write files outside the GPO cache directory as root. On default RHEL configurations     with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication     bypass.(CVE-2026-14476)

    A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates     reply space for all group entries but does not shrink the packet when groups are skipped, causing     uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to disclose     cached directory data and heap layout information from the sssd_nss process.(CVE-2026-68744)

    A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly     configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker     with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all     SSSD-enrolled hosts.(CVE-2026-14474)

    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 service.(CVE-2026-68743)

    A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a     use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could     exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that     disrupts authentication. This vulnerability also presents a potential for privilege escalation, although     it is difficult to exploit.(CVE-2026-12610)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly     configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker     with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all     SSSD-enrolled hosts. (CVE-2026-14474)

    A flaw was found in SSSD. The sss_nss_protocol_parse_addr() function in the NSS responder does not     validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a     crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-of-bounds read and process     crash, resulting in a denial of service.(CVE-2026-68742)

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 service.(CVE-2026-68743)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1984 advisory.

    A flaw was found in the System Security Services Daemon (SSSD). The pam_passkey_child_read_data() function     within the PAM passkey responder fails to properly handle raw bytes received from a pipe. Because the data     is treated as a NUL-terminated C string without explicit termination, it results in an out-of-bounds read     when processed by functions like snprintf(). A local attacker could potentially trigger this vulnerability     by initiating a crafted passkey authentication request, causing the SSSD PAM responder to crash, resulting     in a local Denial of Service (DoS). (CVE-2026-6245)

Tenable has extracted the preceding description block directly from the tested product security advisory.
