Generally, the \"allow_active\" setting in Polkit permits a physically present user to take certain actions based on the session type. Due to the way libblockdev interacts with the udisks daemon, an \"allow_active\" user on a system may be able escalate to full root privileges on the target host. Normally, udisks mounts user-provided filesystem images with security flags like nosuid and nodev to prevent privilege escalation. However, a local attacker can create a specially crafted XFS image containing a SUID-root shell, then trick udisks into resizing it. This mounts their malicious filesystem with root privileges, allowing them to execute their SUID-root shell and gain complete control of the system.", "affected": [ { "packageName": "libblockdev", "collectionURL": "https://github.com/storaged-project/libblockdev/", "defaultStatus": "unaffected", "versions": [ { "version": "0", "status": "affected", "versionType": "semver", "lessThan": "3.3.1" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 10", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:3.2.0-4.el10_0", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 7 Extended Lifecycle Support", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.18-5.el7_9.1", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.28-7.el8_10", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.2 Advanced Update Support", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.19-13.el8_2", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.24-6.el8_4", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.24-9.el8_6", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.6 Telecommunications Update Service", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.24-9.el8_6", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.24-9.el8_6", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.28-3.el8_8", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.28-14.el9_6", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9.0 Update Services for SAP Solutions", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.25-12.el9_0", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.28-5.el9_2", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9.4 Extended Update Support", "packageName": "libblockdev", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "defaultStatus": "affected", "versions": [ { "version": "0:2.28-11.el9_4", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] } ] } } }
