Summary
librsvg regression
Details
USN-4436-1 fixed a vulnerability in librsvg. The upstream fix caused a regression when parsing certain SVG files. This update backs out the fix pending further investigation.
Original advisory details:
It was discovered that librsvg incorrectly handled parsing certain SVG files. A remote attacker could possibly use this issue to cause librsvg to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-11464)
It was discovered that librsvg incorrectly handled parsing certain SVG files with nested patterns. A remote attacker could possibly use this issue to cause librsvg to consume resources and crash, resulting in a denial of service. (CVE-2019-20446)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
