The remote host is affected by the vulnerability described in GLSA-200611-16 (Texinfo: Buffer overflow)

    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.

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.

New Texinfo packages that fix various security vulnerabilities are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Texinfo is a documentation system that can produce both online information and printed output from a single source file.

A buffer overflow flaw was found in Texinfo's texindex command. An attacker could construct a carefully crafted Texinfo file that could cause texindex to crash or possibly execute arbitrary code when opened. (CVE-2006-4810)

A flaw was found in the way Texinfo's texindex command creates temporary files. A local user could leverage this flaw to overwrite files the user executing texindex has write access to. (CVE-2005-3011)

Users of Texinfo should upgrade to these updated packages which contain backported patches and are not vulnerable to these issues.

Specially crafted texinfo files could crash texinfo utilities like texi2dvi and potentially execute code. (CVE-2006-4810)

The remote Solaris system is missing necessary patches to address security updates :

  - Buffer overflow in the readline function in     util/texindex.c, as used by the (1) texi2dvi and (2)     texindex commands, in texinfo 4.8 and earlier allows     local users to execute arbitrary code via a crafted     Texinfo file. (CVE-2006-4810)

Specially crafted texinfo files could crash texinfo utilities.

Miloslav Trmac discovered a buffer overflow in texinfo. This issue can cause texi2dvi or texindex to crash when processing a carefully crafted file.

Updated packages have been patched to correct this issue.

Miloslav Trmac discovered a buffer overflow in texinfo's index processor. If a user is tricked into processing a .texi file with texindex, this could lead to arbitrary code execution with user privileges.
