Heap buffer overflow hibát találtak a pcre reguláris minta kezelőjében. Hibát találtak a poppler rutinkönyvtár a Page osztály konstruktorában és destruktorában, a támadó egy megfelelően preparált pdf állománnyal kódot futtathat a rendszeren. Egész túlcsordulási hibát találtak az OpenOffice.org rtl_allocateMemory() függvényében. A támadó egy megfelelően preparált állománnyal kódot futtathat a rendszeren. Több DoS hibát is találtak az apache-ban: memleak a mod_ssl modulban, ha a kliens támogat tömörítő algoritmusokat, a mod_proxy modul nem limitálja az átmeneti válaszok számát ami memleak-et okoz, valamint egy Cross-Site Request Forgery (CSRF) támadási lehetőséget a mod_proxy_balancer modulban. Az NX valamint NX Node csomagok X.org kódot tartalmaznak, így a GLSA 200806-07 figyelmeztetésben található hibák érintik ezeket a csomagokat is. A Dan Kaminsky által talált DNS cache poisoning hiba javítására kihozták az újabb bind-ot.

Background ========== PCRE is a Perl-compatible regular expression library. GLib includes a copy of PCRE. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libpcre < 7.7-r1 >= 7.7-r1 2 dev-libs/glib < 2.16.3-r1 >= 2.16.3-r1 < 2.14.0 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Tavis Ormandy of the Google Security team reported a heap-based buffer overflow when compiling regular expression patterns containing "Internal Option Settings" such as "(?i)". Impact ====== A remote attacker could exploit this vulnerability by sending a specially crafted regular expression to an application making use of the PCRE library, which could possibly lead to the execution of arbitrary code or a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All PCRE users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libpcre-7.7-r1" All GLib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.16.3-r1" References ========== [ 1 ] CVE-2008-2371 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2371 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200807-03.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.

Background ========== ISC BIND is the Internet Systems Consortium implementation of the Domain Name System (DNS) protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dns/bind < 9.4.2_p1 >= 9.4.2_p1 Description =========== Dan Kaminsky of IOActive has reported a weakness in the DNS protocol related to insufficient randomness of DNS transaction IDs and query source ports. Impact ====== An attacker could exploit this weakness to poison the cache of a recursive resolver and thus spoof DNS traffic, which could e.g. lead to the redirection of web or mail traffic to malicious sites. Workaround ========== There is no known workaround at this time. Resolution ========== All BIND users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/bind-9.4.2_p1" Note: In order to utilize the query port randomization to mitigate the weakness, you need to make sure that your network setup allows the DNS server to use random source ports for query and that you have not set a fixed query port via the "query-source port" directive in the BIND configuration.
