Background ========== aspell is a popular spell-checker. Dictionaries are available for many languages. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/aspell <= 0.50.5-r1 >= 0.50.5-r2 Description =========== aspell includes a utility for handling wordlists called word-list-compress. This utility fails to do proper bounds checking when processing words longer than 256 bytes. Impact ====== If an attacker could entice a user to handle a wordlist containing very long word lengths it could result in the execution of arbitrary code with the permissions of the user running the program. Workaround ========== There is no known workaround at this time. All users are encouraged to upgrade to the latest available version. Resolution ========== All users should upgrade to the latest available version of aspell. # emerge sync # emerge -pv ">=app-text/aspell-0.50.5-r2" # emerge ">=app-text/aspell-0.50.5-r2" References ========== [ 1 ] Nettwerked Advisory http://nettwerked.mg2.org/advisories/wlc Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200406-14.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
