Debian: New texinfo packages fix multiple vulnerabilities

Multiple vulnerabilities have been found in the GNU texinfo package, a documentation system for on-line information and printed output. Handling of temporary files is performed in an insecure manner, allowing an attacker to overwrite any file writable by the victim. A buffer overflow in util/texindex.c could allow an attacker to execute arbitrary code with the victim's access rights by inducing the victim to run texindex or tex2dvi on a specially crafted texinfo file. Fixed packages are available from security.debian.org.

Problem type   : local

Multiple vulnerabilities have been found in the GNU texinfo package, a
documentation system for on-line information and printed output.

CVE-2005-3011
Handling of temporary files is performed in an insecure manner, allowing
an attacker to overwrite any file writable by the victim.

CVE-2006-4810
A buffer overflow in util/texindex.c could allow an attacker to execute
arbitrary code with the victim's access rights by inducing the victim to
run texindex or tex2dvi on a specially crafted texinfo file.

For the stable distribution (sarge), these problems have been fixed in
version 4.7-2.2sarge2  Note that binary packages for the mipsel
architecture are not currently available due to technical problems with
the build host.  These packages will be made available as soon as
possible.

For unstable (sid) and the upcoming stable release (etch), these
problems have been fixed in version 4.8.dfsg.1-4

We recommend that you upgrade your texinfo package.
