U radu programskog paketa Icedove uočeno je više sigurnosnih ranjivosti koje udaljenom napadaču omogućuju zaobilaženje ograničenja u sustavu, napad uskraćivanjem usluga te proizvoljno izvršavanje programskog koda.
Paket:
icedove 3.x
Operacijski sustavi:
Debian Linux 4.0 (etch), Debian Linux 5.0 (lenny), Debian Linux 6.0 (squeeze)
Kritičnost:
10
Problem:
neodgovarajuća provjera ulaznih podataka, nespecificirana pogreška, pogreška u programskoj funkciji, pogreška u programskoj komponenti
Sigurnosni propusti se javljaju zbog pogreške u programskoj funkciji "SVGTextElement.getCharNumAtPosition", nepravilnog rukovanja "RegExp.input" ulaznim podacima, višestrukih nespecificiranih pogrešaka, itd.
Posljedica:
Udaljeni napadač nedostatke može iskoristiti za zaobilaženje postavljenih ograničenja, DoS (eng. Denial of Service) napad te izvršavanje proizvoljnog programskog koda.
Rješenje:
Svim se korisnicima navedenog paketa, u svrhu zaštite sigurnosti, savjetuje njegova nadogradnja na novije inačice.

As indicated in the Lenny (oldstable) release notes, security support for
the Icedove packages in the oldstable needed to be stopped before the end
of the regular Lenny security maintenance life cycle.
You are strongly encouraged to upgrade to stable or switch to a different
mail client.
For the stable distribution (squeeze), this problem has been fixed in
version 3.0.11-1+squeeze4.
For the unstable distribution (sid), this problem has been fixed in
version 3.1.12-1.
We recommend that you upgrade your iceweasel packages.
