Otkriveni su i otklonjeni brojni sigurnosni propusti u programskom paketu Chromium. Potencijalni napadači mogu opisane ranjivosti iskoristiti za proizvoljno izvršavanje programskog koda i DoS napad.
Paket:
Google Chrome 17.x
Operacijski sustavi:
Gentoo Linux
Kritičnost:
7.4
Problem:
neodgovarajuća provjera ulaznih podataka, neodgovarajuće rukovanje memorijom, preljev međuspremnika
Iskorištavanje:
udaljeno
Posljedica:
proizvoljno izvršavanje programskog koda, uskraćivanje usluga (DoS)
Rješenje:
programska zakrpa proizvođača
CVE:
CVE-2011-3031, CVE-2011-3032, CVE-2011-3033, CVE-2011-3034, CVE-2011-3035, CVE-2011-3036, CVE-2011-3037, CVE-2011-3038, CVE-2011-3039, CVE-2011-3040, CVE-2011-3041, CVE-2011-3042, CVE-2011-3043, CVE-2011-3044, CVE-2011-3046, CVE-2011-3047, CVE-2011-3049
Izvorni ID preporuke:
GLSA 201203-19
Izvor:
Gentoo
Problem:
Ranjivosti su posljedica preljeva međuspremnika u komponenti Skia, nepravilne pretvorbe određenih varijabli u drugi tip podataka, neodgovarajuće obrade teksta, greške u podsustavu za upravljanje ekstenzijama, te nepravilno oslobađanje i korištenje slobodne memorije (eng. use-after-free).
Posljedica:
Udaljeni zlonamjeran napadač može iskoristiti propuste za proizvoljno izvršavanje programskog koda i napad uskraćivanjem usluga (DoS napad). Napad podrazumijeva navođenje korisnika na otvaranje zlonamjerno oblikovane web stranice.
Rješenje:
Svim korisnicima se preporuča instalacija službene nadogradnje proizvođača.

Synopsis
========
Multiple vulnerabilities have been reported in Chromium, some of which
may allow execution of arbitrary code.
Background
==========
Chromium is an open source web browser project.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/chromium < 17.0.963.83 >= 17.0.963.83
Description
===========
Multiple vulnerabilities have been discovered in Chromium. Please
review the CVE identifiers and release notes referenced below for
details.
Impact
======
A remote attacker could entice a user to open a specially crafted web
site using Chromium, possibly resulting in the execution of arbitrary
code with the privileges of the process, a Denial of Service condition,
Universal Cross-Site Scripting, or installation of an extension without
user interaction.
A remote attacker could also entice a user to install a specially
crafted extension that would interfere with browser-issued web
requests.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Chromium users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=www-client/chromium-17.0.963.83"
