Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Use-after-free vulnerability in the HTML parser in Mozilla Firefox 3.0.x before 3.0.18 and 3.5.x before 3.5.8, Thunderbird before 3.0.2, and SeaMonkey before 2.0.3 allows remote attackers to execute arbitrary code via unspecified method calls that attempt to access freed objects in low-memory situations.

The weakness was released 02/22/2010 by Martijn Wargers (Paul) with Martijn Wargers as Bug 526500 as not defined bug report (Bugzilla). It is possible to read the advisory at bugzilla.mozilla.org. The identification of this vulnerability is CVE-2009-1571 since 05/06/2009. The exploitation is known to be easy. The attack may be initiated remotely.
