Detailsinfo

A vulnerability was found in GNU C Library 2.1.3.10 on Debian Linux (Software Library). It has been classified as problematic. Affected is an unknown function. The manipulation of the argument LD_DEBUG_OUTPUT/LD_DEBUG as part of a Environment Variable 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 integrity. CVE summarizes:

glibc2 does not properly clear the LD_DEBUG_OUTPUT and LD_DEBUG environmental variables when a program is spawned from a setuid program, which could allow local users to overwrite files via a symlink attack.
