U radu programskog paketa PHP uočen je niz sigurnosnih propusta. Napadač ih može iskoristiti za zaobilaženje pojedinih ograničenja, otkrivanje osjetljivih informacija, izvođenje DoS napada i pokretanje proizvoljnog programskog koda.
Paket:
PHP 5.3.x
Operacijski sustavi:
Gentoo Linux
Kritičnost:
6.2
Problem:
cjelobrojno prepisivanje, pogreška u programskoj funkciji, pogreška u programskoj komponenti
Iskorištavanje:
lokalno/udaljeno
Posljedica:
otkrivanje osjetljivih informacija, proizvoljno izvršavanje programskog koda, uskraćivanje usluga (DoS), zaobilaženje postavljenih ograničenja
Rješenje:
programska zakrpa proizvođača
CVE:
CVE-2006-7243, CVE-2009-5016, CVE-2010-1128, CVE-2010-1129, CVE-2010-1130, CVE-2010-1860, CVE-2010-1861, CVE-2010-1862, CVE-2010-1864, CVE-2010-1866, CVE-2010-1868, CVE-2010-1914, CVE-2010-1915, CVE-2010-1917, CVE-2010-2093, CVE-2010-2094, CVE-2010-2097
Izvorni ID preporuke:
GLSA 201110-06
Izvor:
Gentoo
Problem:
Propusti su posljedica pogrešaka u funkcijama "html_entity_decode", "chunk_split", "addcslashes", "sqlite_single_query", "sqlite_array_query", prepisivanja cijelog broja u funkciji "xml_utf8_decode", nepravilnosti u "safe_mode" implementaciji, itd. Za uvid u sve propuste savjetuje se detaljan pregled izvorne preporuke.
Posljedica:
Napadaču nedostaci omogućuju izvođenje napada uskraćivanja usluge, pokretanje zlonamjernog programskog koda, pregledosjetljivih informacija i zaobilaženje određenih sigurnosnih ograničenja.
Rješenje:
Korisnicima se preporuča instalacija odgovarajuće nadogradnje.

Synopsis
========
Multiple vulnerabilities were found in PHP, the worst of which leading
to remote execution of arbitrary code.
Background
==========
PHP is a widely-used general-purpose scripting language that is
especially suited for Web development and can be embedded into HTML.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/php < 5.3.8 >= 5.3.8
Description
===========
Multiple vulnerabilities have been discovered in PHP. Please review the
CVE identifiers referenced below for details.
Impact
======
A context-dependent attacker could execute arbitrary code, obtain
sensitive information from process memory, bypass intended access
restrictions, or cause a Denial of Service in various ways.
A remote attacker could cause a Denial of Service in various ways,
bypass spam detections, or bypass open_basedir restrictions.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All PHP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.3.8"
