Gentoo Linux Security Advisory
Title: aspell: Buffer overflow in word-list-compress (GLSA 200406-14)
Severity: normal
Exploitable: local
Date: June 17, 2004
Updated: May 22, 2006
Bug(s): #53389
ID: 200406-14
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: app-text/aspell
Vulnerable: <= 0.50.5-r3
Unaffected: >= 0.50.5-r4
Architectures: All supported architectures
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. Code: | # emerge sync
# emerge -pv ">=app-text/aspell-0.50.5-r4"
# emerge ">=app-text/aspell-0.50.5-r4" |
