Bug 128107 – app-office/dia: Buffer overflow in xfig import (CVE-2006-1550)

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Eduardo Tongson 2006-03-30 07:03:40 UTC]

A voluntary security review of the importers by infamous41md has turned
up three buffer overflow errors in the xfig import code.  These errors
have existed since the code was first created in version 0.87, but are
corrected as of version 0.95-pre6.  The attached patch fixes them for
version 0.94.

I've done some testing with dia-0.94-r5 [-debug +gnome +png +python -static +zlib] on x86. A really nice application that seems to work fine (i wish i had discovered this app a few weeks earlier) ...
