Low risk2th percentile - higher than 2% of all known CVEs
Summary
A flaw was found in librsvg where processing an SVG document with nested XML inclusions (Xincludes) and duplicate entity declarations can cause a use-after-free. The library incorrectly frees an XML entity still in use by the parser. An attacker could exploit this to cause a denial of service or execute arbitrary code.
Risk Assessment
Processing a malicious SVG file may crash the application or execute arbitrary code in the context of the image-processing process.
Recommendation
Update librsvg to a patched version and avoid processing untrusted SVG documents in critical services.
Other vulnerabilities in librsvg
See all- CVE-2016-4348High
The _rsvg_css_normalize_font_size function in librsvg 2.40.2 allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via circular definitions in an SVG document.
- CVE-2015-7558High
Librsvg before version 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-2015-7557High
The _rsvg_node_poly_build_path function in librsvg before version 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-2023-38633Medium
A directory traversal issue in the URL decoder of librsvg before version 2.56.3 could be exploited by local or remote attackers to disclose files from the local filesystem outside of the expected area.
Original NVD description (English source)
A flaw was found in librsvg. When processing an SVG document containing nested XML inclusions (Xincludes) with duplicate entity declarations, a use-after-free error can occur. This vulnerability arises because the library incorrectly frees an XML entity that is still in use by the parser. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code.
