Descriptions

The distcheck rule in dist-check.mk in GNU coreutils 5.2.1 through 8.1 allows local users to gain privileges via a symlink attack on a file in a directory tree under /tmp.

La regla distcheck en dist-check.mk en GNU coreutils desde v5.2.1 hasta v8.1 permite a usuarios locales ganar privilegios a través de un ataque de enlace simbólico en un fichero que este en la carpeta /tmp.

It was discovered that the distcheck rule in dist-check.mk in GNU coreutils allows local users to gain privileges via a symlink attack on a directory tree under /tmp. This issue only affected Ubuntu 10.04 LTS. Bertrand Jacquin and Fiedler Roman discovered date and touch incorrectly handled user-supplied input. An attacker could possibly use this to cause a denial of service or potentially execute code. Various other issues were also addressed.
