librsvg before 2.40.12 allows context-dependent attackers to cause a denial of service (infinite loop, stack consumption, and application crash) via cyclic references in an SVG document.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - librsvg before 2.40.12 allows context-dependent attackers to cause a denial of service (infinite loop,     stack consumption, and application crash) via cyclic references in an SVG document. (CVE-2015-7558)

Note that Nessus relies on the presence of the package as reported by the vendor.

According to the versions of the librsvg2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - librsvg before 2.40.12 allows context-dependent     attackers to cause a denial of service (infinite loop,     stack consumption, and application crash) via cyclic     references in an SVG document.(CVE-2015-7558)

  - The _rsvg_node_poly_build_path function in     rsvg-shapes.c in librsvg before 2.40.7 allows     context-dependent attackers to cause a denial of     service (out-of-bounds heap read) via an odd number of     elements in a coordinate pair in an SVG     document.(CVE-2015-7557)

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.

Gustavo Grieco discovered several flaws in the way librsvg, a SAX-based renderer library for SVG files, parses SVG files with circular definitions. A remote attacker can take advantage of these flaws to cause an application using the librsvg library to crash.

(Note CVE-2016-4347 is a duplicate of CVE-2015-7558)

Two DoS in librsvg 2.40.2 parsing SVGs with circular definitions were found (they will produce stack exhaustion) by Gustavo Grieco.

The version in wheezy (2.36.1-2+deb7u1) is also vulnerable.

For Debian 7 'Wheezy', these problems have been fixed in version 2.36.1-2+deb7u2.

We recommend that you upgrade your librsvg packages.

Adam Maris, Red Hat Product Security, reports :

CVE-2015-7558: Stack exhaustion due to cyclic dependency causing to crash an application was found in librsvg2 while parsing SVG file. It has been fixed in 2.40.12 by many commits that has rewritten the checks for cyclic references.
