"The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2012:1201 advisory.

    teTeX is an implementation of TeX. TeX takes a text file and a set of
    formatting commands as input, and creates a typesetter-independent DeVice
    Independent (DVI) file as output.

    teTeX embeds a copy of t1lib to rasterize bitmaps from PostScript Type 1
    fonts. The following issues affect t1lib code:

    Two heap-based buffer overflow flaws were found in the way t1lib processed
    Adobe Font Metrics (AFM) files. If a specially-crafted font file was opened
    by teTeX, it could cause teTeX to crash or, potentially, execute arbitrary
    code with the privileges of the user running teTeX. (CVE-2010-2642,
    CVE-2011-0433)

    An invalid pointer dereference flaw was found in t1lib. A specially-crafted
    font file could, when opened, cause teTeX to crash or, potentially, execute
    arbitrary code with the privileges of the user running teTeX.
    (CVE-2011-0764)

    A use-after-free flaw was found in t1lib. A specially-crafted font file
    could, when opened, cause teTeX to crash or, potentially, execute arbitrary
    code with the privileges of the user running teTeX. (CVE-2011-1553)

    An off-by-one flaw was found in t1lib. A specially-crafted font file could,
    when opened, cause teTeX to crash or, potentially, execute arbitrary code
    with the privileges of the user running teTeX. (CVE-2011-1554)

    An out-of-bounds memory read flaw was found in t1lib. A specially-crafted
    font file could, when opened, cause teTeX to crash. (CVE-2011-1552)

    teTeX embeds a copy of Xpdf, an open source Portable Document Format (PDF)
    file viewer, to allow adding images in PDF format to the generated PDF
    documents. The following issues affect Xpdf code:

    An uninitialized pointer use flaw was discovered in Xpdf. If pdflatex was
    used to process a TeX document referencing a specially-crafted PDF file, it
    could cause pdflatex to crash or, potentially, execute arbitrary code with
    the privileges of the user running pdflatex. (CVE-2010-3702)

    An array index error was found in the way Xpdf parsed PostScript Type 1
    fonts embedded in PDF documents. If pdflatex was used to process a TeX
    document referencing a specially-crafted PDF file, it could cause pdflatex
    to crash or, potentially, execute arbitrary code with the privileges of the
    user running pdflatex. (CVE-2010-3704)

    Red Hat would like to thank the Evince development team for reporting
    CVE-2010-2642. Upstream acknowledges Jon Larimer of IBM X-Force as the
    original reporter of CVE-2010-2642.

    All users of tetex are advised to upgrade to these updated packages, which
    contain backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
