Format string vulnerability in the yyerror function in lib/cgraph/scan.l in Graphviz allows remote attackers to have unspecified impact via format string specifiers in unknown vectors, which are not properly handled in an error string.

The remote Redhat Enterprise Linux 7 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.

  - graphviz: format string vulnerability in yyerror() (CVE-2014-9157)

  - graphviz: null pointer dereference in function agroot() in cgraph\obj.c (CVE-2019-11023)

  - An issue was discovered in lib\cdt\dttree.c in libcdt.a in graphviz 2.40.1. Stack consumption occurs     because of recursive agclose calls in lib\cgraph\graph.c in libcgraph.a, related to agfstsubg in     lib\cgraph\subg.c. (CVE-2019-9904)

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 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.

  - graphviz: stack-based buffer overflow in chkNum() (CVE-2014-1236)

  - graphviz: recursive function call in agclose in lib\cgraph\graph.c causing stack consumption     (CVE-2019-9904)

  - Stack-based buffer overflow in the yyerror function in lib/cgraph/scan.l in Graphviz 2.34.0 allows remote     attackers to have unspecified impact via a long line in a dot file. (CVE-2014-0978)

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

According to the version of the graphviz packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - Format string vulnerability in the yyerror function in     lib/cgraph/scan.l in Graphviz allows remote attackers     to have unspecified impact via format string specifiers     in unknown vectors, which are not properly handled in     an error string.(CVE-2014-9157)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update for graphviz fixes the following issues :

Security issue fixed :

  - CVE-2014-9157: Fix format string vulnerability     (boo#908426).

Updated graphviz packages fix security vulnerability :

Format string vulnerability in the yyerror function in lib/cgraph/scan.l in Graphviz allows remote attackers to have unspecified impact via format string specifiers in unknown vector, which are not properly handled in an error string (CVE-2014-9157).

Additionally the gtkglarea2 and gtkglext packages were missing and was required for graphviz to build, these packages are also being provided with this advisory.

Joshua Rogers discovered a format string vulnerability in the yyerror function in lib/cgraph/scan.l in Graphviz, a rich set of graph drawing tools. An attacker could use this flaw to cause graphviz to crash or possibly execute arbitrary code.
