The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-203:01 advisory.

    TeXLive 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 printable 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.
    Install texlive if you want to use the TeX text formatting system. Consider to install texlive-latex (a     higher level formatting package which provides an easier-to-use interface for TeX).
    The TeX documentation is located in the texlive-doc package.
    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-2011-0433     No description available, see the CVE links 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.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

A vulnerability has been found and corrected in t1lib :

t1lib 5.1.2 and earlier uses an invalid pointer in conjunction with a dereference operation, which allows remote attackers to execute arbitrary code via a specially crafted Type 1 font in a PDF document (CVE-2011-0764).

The updated packages have been patched to correct this issue.

This update of t1lib fixes memory corruptions and a heap-based overflow in the afm font parser.

TeX Live embeds a copy of t1lib. The t1lib library allows you 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 a TeX Live utility, it could cause the utility to crash or, potentially, execute arbitrary code with the privileges of the user running the utility. (CVE-2010-2642 , CVE-2011-0433)

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

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

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

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

Updated tetex packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.
