Description
This security bulletin contains information about 3 vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2025-6965)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing aggregated terms. A remote attacker can pass specially crafted input to the application where the number of aggregate terms exceeds the number of columns available, trigger memory corruption and perform a denial of service (DoS) attack.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2025-4598)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists in systemd-coredump when handling process crashes. A local user who can force a SUID process to crash can replace it with a non-SUID binary to access the original's privileged process coredump and read sensitive data, such as /etc/shadow content, loaded by the original process.
3) Race condition (CVE-ID: CVE-2025-40909)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to tamper with application's behavior.
The vulnerability exists due to a race condition if a directory handle is open at thread creation. A local user can exploit the race and force the application to load code or access files from unexpected location.
