Synopsis
========
Texinfo is vulnerable to a buffer overflow that could lead to the
execution of arbitrary code.
Background
==========
Texinfo is the official documentation system of the GNU project.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-apps/texinfo < 4.8-r5 >= 4.8-r5
Description
===========
Miloslav Trmac from Red Hat discovered a buffer overflow in the
"readline()" function of texindex.c. The "readline()" function is
called by the texi2dvi and texindex commands.
Impact
======
By enticing a user to open a specially crafted Texinfo file, an
attacker could execute arbitrary code with the rights of the user
running Texinfo.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Texinfo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/texinfo-4.8-r5"
References
==========
