Integer overflow in the gs_heap_alloc_bytes function in base/gsmalloc.c in Ghostscript 9.15 and earlier allows remote attackers to cause a denial of service (crash) via a crafted Postscript (ps) file, as demonstrated by using the ps2pdf command, which triggers an out-of-bounds read or write.

According to the version of the ghostscript package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - An integer overflow flaw was discovered in one of     Ghostscript's memory allocation routines. A remote     attacker could possibly exploit this flaw to cause a     crash or, potentially, execute arbitrary code by     tricking a user into processing a specially crafted     file.i1/4^CVE-2015-3228i1/4%0

The remote host is affected by the vulnerability described in GLSA-201612-33 (GPL Ghostscript: User-assisted execution of arbitrary code)

    An integer overflow flaw was discovered that leads to an out-of-bounds       read and write in gs_ttf.ps.
  Impact :

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

    There is no known workaround at this time.

This update for ghostscript-library fixes the following issues :

  - Multiple security vulnerabilities have been discovered     where ghostscript's '-dsafer' flag did not provide     sufficient protection against unintended access to the     file system. Thus, a machine that would process a     specially crafted Postscript file would potentially leak     sensitive information to an attacker. (CVE-2013-5653,     CVE-2016-7977, bsc#1001951)

  - Insufficient validation of the type of input in     .initialize_dsc_parser used to allow remote code     execution. (CVE-2016-7979, bsc#1001951)

  - An integer overflow in the gs_heap_alloc_bytes function     used to allow remote attackers to cause a denial of     service (crash) via specially crafted Postscript files.
    (CVE-2015-3228, boo#939342)

ghostscript was updated to fix one security issue and one bug.

The following vulnerability was fixed :

  - CVE-2015-3228: Specially crafted ps files could have     caused an out of bound read/write due to an integer     overflow, causing a segfault in the application or     having unspecified further impact.

Also a non security bug was fixed :

  - fix a crash in mutex handling (bsc#963017)

This update was imported from the SUSE:SLE-12:Update update project.

ghostscript was updated to fix one security issue and one bug.

MITRE reports :

Integer overflow in the gs_heap_alloc_bytes function in base/gsmalloc.c in Ghostscript 9.15 and earlier allows remote attackers to cause a denial of service (crash) via a crafted Postscript (ps) file, as demonstrated by using the ps2pdf command, which triggers an out-of-bounds read or write.

Ghostscript was updated to fix one security issue.

The following vulnerability was fixed :

  - CVE-2015-3228: Specially crafted files could have caused     an interger overflow, resulting in a crash of the     application or unspecified other impact (bsc#939342)

William Robinet and Stefan Cornelius discovered an integer overflow in Ghostscript, the GPL PostScript/PDF interpreter, which may result in denial of service or potentially execution of arbitrary code if a specially crafted file is opened.

William Robinet and Stefan Cornelius discovered that Ghostscript did not correctly handle certain Postscript files. If a user or automated system were tricked into opening a specially crafted file, an attacker could cause a denial of service or possibly execute arbitrary code.

In gs_heap_alloc_bytes(), add a sanity check to ensure we don't overflow the variable holding the actual number of bytes we allocate.
