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.

The remote host is affected by the vulnerability described in GLSA-201701-57 (T1Lib: : Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in T1Lib. Please review       the CVE identifiers referenced below for details.
  Impact :

    Remote attackers, by coercing users to process specially crafted AFM       font or PDF file, could cause a Denial of Service condition or execute       arbitrary code.
  Workaround :

    There is no known workaround at this time.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-906:01 advisory.

    TeTeX is an implementation of TeX for Linux or UNIX systems. TeX takes a text file and a set of formatting     commands as input and creates a typesetter-independent .dvi (DeVice Independent) file as output. Usually,     TeX is used in conjunction with a higher level formatting package like LaTeX or PlainTeX, since TeX by     itself is not very user-friendly. The output format needn't to be DVI, but also PDF, when using pdflatex     or similar tools.
    Install tetex if you want to use the TeX text formatting system. Consider to install tetex-latex (a higher     level formatting package which provides an easier-to-use interface for TeX). Unless you are an expert at     using TeX, you should also install the tetex-doc package, which includes the documentation for TeX.
    Security issues fixed with this release :
     CVE-2010-2642     Heap-based buffer overflow in the AFM font parser in the dvi-backend component in Evince 2.32 and earlier,     teTeX 3.0, t1lib 5.1.2, and possibly other products allows remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code via a crafted font in conjunction with a DVI file     that is processed by the thumbnailer.
     CVE-2010-3702     The Gfx::getPos function in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7 and possibly other     versions up to 0.15.1, CUPS, kdegraphics, and possibly other products allows context-dependent attackers     to cause a denial of service (crash) via unknown vectors that trigger an uninitialized pointer     dereference.
     CVE-2010-3704     The FoFiType1::parse function in fofi/FoFiType1.cc in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7     and possibly other versions up to 0.15.1, kdegraphics, and possibly other products allows context-     dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PDF     file with a crafted Type1 font that contains a negative array index, which bypasses input validation and     which triggers memory corruption.
     CVE-2011-0433     No description available at the time of writing, please use the CVE link below.
     CVE-2011-0764     t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6 and other products, uses an invalid pointer in     conjunction with a dereference operation, which allows remote attackers to execute arbitrary code via a     crafted Type 1 font in a PDF document, as demonstrated by testz.2184122398.pdf.
     CVE-2011-1552     t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6 and other products, reads from invalid memory     locations, which allows remote attackers to cause a denial of service (application crash) via a crafted     Type 1 font in a PDF document, a different vulnerability than CVE-2011-0764.
     CVE-2011-1553     Use-after-free vulnerability in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6 and other     products, allows remote attackers to cause a denial of service (application crash) via a PDF document     containing a crafted Type 1 font that triggers an invalid memory write, a different vulnerability than     CVE-2011-0764.
     CVE-2011-1554     Off-by-one error in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6 and other products, allows     remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted     Type 1 font that triggers an invalid memory read, integer overflow, and invalid pointer dereference, a     different vulnerability than CVE-2011-0764.

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

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 t1lib are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All applications linked against t1lib must be restarted for this update to take effect.

This update fixes several security flaws in t1lib (flaws in AFM parser and when handling specially crafted Type1 fonts).
