"The remote MiracleLinux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the
AXSA:2012-77:01 advisory.

    T1lib is a rasterizer library for Adobe Type 1 Fonts. It supports rotation and transformation, kerning
    underlining and antialiasing. It does not depend on X11, but does provides some special functions for X11.
    AFM-files can be generated from Type 1 font files and font subsetting is possible.
    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 information available at the time of writing, see the 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.
