Description
This security bulletin contains information about 2 vulnerabilities.
1) Race condition (CVE-ID: CVE-2024-45310)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to crate empty files and directories on the host.
The vulnerability exists due to a race condition when handling containers with custom configuration. A remote attacker can trick the victim into running a specially crafted Docker or Kubernetes container, which can be used to share a volume between two containers and then exploit a race with os.MkdirAll to create empty files or directories in arbitrary locations in the host filesystem.
Successful exploitation of the vulnerability may allow an attacker to perform a denial of service attack against the host system.
2) Improper Check or Handling of Exceptional Conditions (CVE-ID: CVE-2025-64435)
CWE-ID: CWE-703 - Improper Check or Handling of Exceptional Conditions
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper conditions check in the virt-controller. A remote user can pass specially crafted input to the application and cause a denial of service condition on the target system.
