| Description: | If was discovered that Firefox could be made to access freed memory. If a user were tricked into viewing a malicious site, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. This issue only affected Ubuntu 8.04 LTS. Several flaws were discovered in the browser engine of Firefox. If a user were tricked into viewing a malicious site, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. A flaw was discovered in the way plugin instances interacted. An attacker could potentially exploit this and use one plugin to access freed memory from a second plugin to execute arbitrary code with the privileges of the user invoking the program. An integer overflow was discovered in Firefox. If a user were tricked into viewing a malicious site, an attacker could overflow a buffer and cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. Martin Barbella discovered an integer overflow in an XSLT node sorting routine. An attacker could exploit this to overflow a buffer and cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program.
