Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Infinite loop (CVE-ID: CVE-2025-8194)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in the “tarfile” module when handling tar archives with negative offsets. A remote attacker can pass a specially crafted tar archive to the application and consume all available system resources, resulting in a deadlock and a denial of service.
2) Link following (CVE-ID: CVE-2025-8941)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an insecure link following issue in the pam_namespace module. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
The vulnerability exists due to incomplete fix for #VU111389 (CVE-2025-6020).
3) Uncontrolled Recursion (CVE-ID: CVE-2025-48924)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the methods ClassUtils.getClass(...) can throw StackOverflowError on very long inputs. Because an Error is usually not handled by applications and libraries, a StackOverflowError could cause an application to stop. A remote attacker can trigger uncontrolled recursion and perform a denial of service (DoS) attack.
4) Out-of-bounds read (CVE-ID: CVE-2025-32414)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to an out-of-bounds read that occurs in the Python API (Python bindings) because of an incorrect return value. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Race condition (CVE-ID: CVE-2025-47907)
The vulnerability allows an attacker to tamper with the application.
The vulnerability exists due to a race condition when canceling a DB query. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system. A remote user can overwrite the expected results with those of another query, causing the call to Scan to return either unexpected results from the other query or an error.
