Detailsinfo

A vulnerability was found in FreeBSD 4.0/4.1/4.2/4.3 (Operating System). It has been classified as problematic. Affected is an unknown code of the component linprocfs. The manipulation with an unknown input leads to a information disclosure vulnerability (Memory). CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

linprocfs on FreeBSD 4.3 and earlier does not properly restrict access to kernel memory, which allows one process with debugging rights on a privileged process to read restricted memory from that process.

The weakness was released 08/21/2001 by Joost Pol (Website). The advisory is shared for download at ftp.freebsd.org. This vulnerability is traded as CVE-2001-1166. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (7017), SecurityFocus (BID 3217†), OSVDB (1938†) and Vulnerability Center (SBV-22765†). Once again VulDB remains the best source for vulnerability data.
