If a remote attacker does not authenticate within a set time period, then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). As a consequence of a successful attack, in the worst case scenario, an attacker may be able to perform a remote code execution (RCE) as an unprivileged user running the sshd server." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "Signal Handler Race Condition", "cweId": "CWE-364" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Red Hat", "product": { "product_data": [ { "product_name": "Red Hat Enterprise Linux 9", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:8.7p1-38.el9_4.4", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:8.7p1-38.el9_4.4", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 9.0 Update Services for SAP Solutions", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:8.7p1-12.el9_0.3", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 9.2 Extended Update Support", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:8.7p1-30.el9_2.7", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat OpenShift Container Platform 4.13", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "413.92.202408122222-0", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat OpenShift Container Platform 4.14", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "414.92.202407300859-0", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat OpenShift Container Platform 4.15", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "415.92.202407301159-0", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat OpenShift Container Platform 4.16", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "416.94.202407171205-0", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 6", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 7", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 8", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://access.redhat.com/errata/RHSA-2024:4457", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:4457" }, { "url": "https://access.redhat.com/errata/RHSA-2024:4613", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:4613" }, { "url": "https://access.redhat.com/errata/RHSA-2024:4716", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:4716" }, { "url": "https://access.redhat.com/errata/RHSA-2024:4910", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:4910" }, { "url": "https://access.redhat.com/errata/RHSA-2024:4955", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:4955" }, { "url": "https://access.redhat.com/errata/RHSA-2024:4960", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:4960" }, { "url": "https://access.redhat.com/errata/RHSA-2024:5444", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:5444" }, { "url": "https://access.redhat.com/security/cve/CVE-2024-6409", "refsource": "MISC", "name": "https://access.redhat.com/security/cve/CVE-2024-6409" }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2295085", "refsource": "MISC", "name": "https://bugzilla.redhat.com/show_bug.cgi?id=2295085" } ] }, "work_around": [ { "lang": "en", "value": "The process is identical to CVE-2024-6387, by disabling LoginGraceTime.
