Package : flex
Vulnerability : buffer overflow
Problem-Type : local
Debian-specific: no
CVE ID : CVE-2006-0459
Chris Moore discovered that flex, a scanner generator, generates
code, which allocates insufficient memory, if the grammar contains
REJECT statements or trailing context rules. This may lead to a
buffer overflow and the execution of arbitrary code.
If you use code, which is derived from a vulnerable lex grammar
in an untrusted environment you need to regenerate your scanner
with the fixed version of flex.
The old stable distribution (woody) is not affected by this
problem.
For the stable distribution (sarge) this problem has been fixed
in version 2.5.31-31sarge1.
For the unstable distribution (sid) this problem has been fixed
in version 2.5.33-1.
We recommend that you upgrade your flex package.
Upgrade Instructions

Title: OpenOffice.org:Heap overflow in included libcurl
Date: March 27, 2006
Bugs: #126433
ID: 200603-25
Synopsis
OpenOffice.org contains a vulnerable version of libcurl that may
cause a heap overflow when parsing URLs.
Background
OpenOffice.org is an office productivity suite, including word
processing, spreadsheet, presentation, data charting, formula
editing and file conversion facilities. libcurl, which is included
in OpenOffice.org, is a free and easy-to-use client-side library
for transferring files with URL syntaxes, supporting numerous
protocols.
Affected packages
Package / Vulnerable / Unaffected
1 app-office/openoffice-bin < 2.0.2 >= 2.0.2 2 app-office/openoffice < 2.0.1-r1 >= 2.0.1-r1 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures.
Description
OpenOffice.org includes libcurl code. This libcurl code is
vulnerable to a heap overflow when it tries to parse a URL that
exceeds a 256-byte limit (GLSA 200512-09).
Impact
An attacker could entice a user to call a specially crafted URL
with OpenOffice.org, potentially resulting in the execution of
arbitrary code with the rights of the user running the
application.
Workaround
There is no known workaround at this time.
Resolution
All OpenOffice.org binary users should upgrade to the latest
version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.0.2"
All OpenOffice.org users should upgrade to the latest
version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-office/openoffice-2.0.1-r1"
