Description Josh Bressers 2005-02-28 21:05:35 UTC
Daniel de Wildt discovered a memory handling flaw in Mozilla string classes that
could overwrite memory at a fixed location if reallocation fails during string
growth. This could theoretically lead to arbitrary code execution. Creating the
exact conditions for exploitation--including running out of memory at just the
right moment--is unlikely.

This flaw was independently discovered by Gaël Delalleau and reported by iDEFENSE
