"When rendering glyphs, the cairo graphics rendering library did not
check the maximum length of character strings. A request to display an
excessively long string with cairo caused a program crash due to an X
library error.

Mike Davis discovered that this could be turned into a Denial of
Service attack in Evolution. An email with an attachment with very
long lines caused Evolution to crash repeatedly until that email was
manually removed from the mail folder.

This only affects Ubuntu 5.10. Previous Ubuntu releases did not use
libcairo for text rendering.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
