Chris Moore discovered a buffer overflow in a particular class of
lexicographical scanners generated by flex. This could be exploited to
execute arbitrary code by processing specially crafted user-defined
input to an application that uses a flex scanner for parsing.
This flaw particularly affects gpc, the GNU Pascal Compiler. A
potentially remote attacker could exploit this by tricking an user or
automated system into compiling a specially crafted Pascal source code
Please note that gpc is not officially supported in Ubuntu (it is in
the 'universe' component of the archive). However, this affects you if
you use a customized version built from the gcc-3.3 or gcc-3.4 source
package (which is supported).
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.
Update the affected packages.
