Synopsis ========
A bug in the aspell utility word-list-compress can allow an attacker to execute arbitrary code.
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"
