CVE-2007-0778: Canonical Ubuntu Linux

Medium severity, CVSS 5.4. EPSS: 3.2% chance of exploitation in the next 30 days.

The page cache feature in Mozilla Firefox before 1.5.0.10 and 2.x before 2.0.0.2, and SeaMonkey before 1.0.8 can generate hash collisions that cause page data to be appended to the wrong page cache, which allows remote attackers to obtain sensitive information or enable further attack vectors when the target page is reloaded from the cache.

Affected products

• Canonical Ubuntu Linux: version 5.10 only; version 6.06 only; version 6.10 only
• Debian Debian Linux: version 3.1 only
• Mozilla Firefox: from 1.5, before 1.5.0.10 (fixed in 1.5.0.10); from 2.0, before 2.0.0.2 (fixed in 2.0.0.2)
• Mozilla Seamonkey: before 1.0.8 (fixed in 1.0.8)
