Read beyond buffer while parsing XML

Announced

February 1, 2006

Reporter

Johnny Stenback

Impact

Low

Products

Firefox, SeaMonkey, Thunderbird

Fixed in

• Firefox 1.5.0.1
• SeaMonkey 1
• Thunderbird 1.5.0.2

Description

An upgrade in the XML parser introduced a bug that could read beyond the end of the buffer, often causing a crash. We don't know if this could be exploited to incorporate private data into the DOM of an XML document, but could be a privacy risk if so. Firefox 1.0, Thunderbird 1.0 and Mozilla Suite 1.7 are not affected.

Update (13 April 2006)
This flaw has been fixed in Thunderbird 1.5.0.2

Workaround

Upgrade to the fixed versions.
