Stack-based buffer overflow in Xfig 3.2.4 and 3.2.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a FIG image with a crafted color definition.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Xfig, Transfig: Stack-based buffer overflow by loading malformed .FIG files (CVE-2009-4228)

  - Xfig: Stack-based buffer overflow by processing certain FIG images (CVE-2010-4262)

  - Xfig, possibly 3.2.5, allows local users to read and write arbitrary files via a symlink attack on the (1)     xfig-eps[PID], (2) xfig-pic[PID].pix, (3) xfig-pic[PID].err, (4) xfig-pcx[PID].pix, (5) xfig-xfigrc[PID],     (6) xfig[PID], (7) xfig-print[PID], (8) xfig-export[PID].err, (9) xfig-batch[PID], (10) xfig-exp[PID], or     (11) xfig-spell.[PID] temporary files, where [PID] is a process ID. (CVE-2009-1962)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Xfig, Transfig: Stack-based buffer overflow by loading malformed .FIG files (CVE-2009-4228)

  - Xfig: Stack-based buffer overflow by processing certain FIG images (CVE-2010-4262)

  - Xfig, possibly 3.2.5, allows local users to read and write arbitrary files via a symlink attack on the (1)     xfig-eps[PID], (2) xfig-pic[PID].pix, (3) xfig-pic[PID].err, (4) xfig-pcx[PID].pix, (5) xfig-xfigrc[PID],     (6) xfig[PID], (7) xfig-print[PID], (8) xfig-export[PID].err, (9) xfig-batch[PID], (10) xfig-exp[PID], or     (11) xfig-spell.[PID] temporary files, where [PID] is a process ID. (CVE-2009-1962)

The remote Redhat Enterprise Linux 4 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Xfig, Transfig: Stack-based buffer overflow by loading malformed .FIG files (CVE-2009-4228)

  - Xfig: Stack-based buffer overflow by processing certain FIG images (CVE-2010-4262)

The remote host is affected by the vulnerability described in GLSA-201312-16 (Xfig: Arbitrary code execution)

    Xfig contains a buffer overflow vulnerability in processing certain FIG       images.
  Impact :

    A remote attacker could entice a user to open a specially crafted file,       potentially resulting in arbitrary code execution or a Denial of Service       condition.
  Workaround :

    There is no known workaround at this time.

Multiple vulnerabilities has been found and corrected in xfig :

Stack-based buffer overflow in the read_1_3_textobject function in f_readold.c in Xfig 3.2.5b and earlier, and in the read_textobject function in read1_3.c in fig2dev in Transfig 3.2.5a and earlier, allows remote attackers to execute arbitrary code via a long string in a malformed .fig file that uses the 1.3 file format. NOTE: some of these details are obtained from third-party information (CVE-2009-4227).

Stack consumption vulnerability in u_bound.c in Xfig 3.2.5b and earlier allows remote attackers to cause a denial of service (application crash) via a long string in a malformed .fig file that uses the 1.3 file format, possibly related to the readfp_fig function in f_read.c (CVE-2009-4228).

Stack-based buffer overflow in Xfig 3.2.4 and 3.2.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a FIG image with a crafted color definition (CVE-2010-4262).
