Detailsinfo

A vulnerability classified as critical has been found in HP Secure OS up to 7.3. Affected is some unknown functionality of the file setpwnam.c of the component util-linux Package. The manipulation with an unknown input leads to a symlink vulnerability. CWE is classifying the issue as CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

setpwnam.c in the util-linux package, as included in Red Hat Linux 7.3 and earlier, and other operating systems, does not properly lock a temporary file when modifying /etc/passwd, which may allow local users to gain privileges via a complex race condition that uses an open file descriptor in utility programs such as chfn and chsh.

The weakness was shared 07/29/2002 by Michal Zalewski with Core as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability is traded as CVE-2002-0638. The exploitability is told to be difficult. Local access is required to approach this attack. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 13950 (Mandrake Linux Security Advisory : util-linux (MDKSA-2002:047)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (37477), Tenable (13950), SecurityFocus (BID 5344†), OSVDB (5164†) and Secunia (SA7413†). If you want to get best quality of vulnerability data, you may have to visit VulDB.
