Attack vector
LOCAL Attack complexity
HIGH Privileges required
LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
Race condition in the fsnotify implementation in the Linux kernel through 4.12.4 allows local users to gain privileges or cause a denial of service (memory corruption) via a crafted application that leverages simultaneous execution of the inotify_handle_event and vfs_rename functions.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Leveraging Race Conditions This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
- Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

Unfortunately, a regression was introduced that prevented conntrack from working correctly in some situations. This update fixes the problem. We apologize for the inconvenience. Fan Wu and Shixiong Zhao discovered a race condition between inotify events and vfs rename operations in the Linux kernel. An unprivileged local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2017-7533) It was discovered that the Linux kernel did not properly restrict RLIMIT_STACK size. A local attacker could use this in conjunction with another vulnerability to possibly execute arbitrary code.

This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. USN-3378-2 fixed vulnerabilities in the Linux Hardware Enablement kernel. Unfortunately, a regression was introduced that prevented conntrack from working correctly in some situations. This update fixes the problem. We apologize for the inconvenience. Fan Wu and Shixiong Zhao discovered a race condition between inotify events and vfs rename operations in the Linux kernel. An unprivileged local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2017-7533) It was discovered that the Linux kernel did not properly restrict RLIMIT_STACK size. A local attacker could use this in conjunction with another vulnerability to possibly execute arbitrary code. (CVE-2017-1000365) Li Qiang discovered that the Virtio GPU driver in the Linux kernel did not properly free memory in some situations. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-10810) Shi Lei discovered that the RxRPC Kerberos 5 ticket handling code in the Linux kernel did not properly verify metadata.
