GNU C Library up to 2.3.10 symlink

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as problematic was found in GNU C Library (Software Library). Affected by this vulnerability is an unknown functionality. The manipulation with an unknown input leads to a symlink vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect integrity. The summary by CVE is:

The glibcbug script in glibc 2.3.4 and earlier allows local users to overwrite arbitrary files via a symlink attack on temporary files, a different vulnerability than CVE-2004-0968.

The bug was discovered 04/28/2004. The weakness was released 12/31/2004 (Website). The advisory is shared at debian.org. This vulnerability is known as CVE-2004-1382 since 01/28/2005. The exploitation appears to be easy. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 247 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 16150 (Debian DSA-636-1 : glibc - insecure temporary files), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117974 (CentOS Security Update for glibc (CESA-2005:261)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (21150), Tenable (16150), SecurityFocus (BID 11286†), OSVDB (13933†) and Vulnerability Center (SBV-7786†). Entries connected to this vulnerability are available at VDB-942 and VDB-22746. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
