Untrusted search path vulnerability in Mozilla Network Security Services might allow local users to gain privileges via a Trojan horse pkcs11.txt file in a top-level directory . Cross-site scripting vulnerability in Mozilla Firefox before 3.6.24 and 4.x through 7.0 and Thunderbird before 3.1.6 and 5.0 through 7.0 allows remote attackers to inject arbitrary web script or HTML via crafted text with Shift JIS encoding . Mozilla Firefox before 3.6.24 and 4.x through 7.0 and Thunderbird before 3.1.6 and 5.0 through 7.0 do not properly handle JavaScript files that contain many functions, which allows user-assisted remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted file that is accessed by debugging APIs, as demonstrated by Firebug . The following vulnerabilities affetst Mandriva Linux 2011 only: Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 7.0 and Thunderbird 7.0 allow remote attackers to cause a denial of service or possibly execute arbitrary code via unknown vectors . The browser engine in Mozilla Firefox before 8.0 and Thunderbird before 8.0 does not properly allocate memory, which allows remote attackers to cause a denial of service or possibly execute arbitrary code via unspecified vectors . The browser engine in Mozilla Firefox before 8.0 and Thunderbird before 8.0 does not properly handle links from SVG mpath elements to non-SVG elements, which allows remote attackers to cause a denial of service or possibly execute arbitrary code via unspecified vectors . Mozilla Firefox 4.x through 7.0 and Thunderbird 5.0 through 7.0 perform access control without checking for use of the NoWaiverWrapper wrapper, which allows remote attackers to gain privileges via a crafted web site .
