libxml2 2.9.4, when used in recover mode, allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted XML document. NOTE: The maintainer states "I would disagree of a CVE with the Recover parsing option which should only be used for manual recovery at least for XML parser.
A NULL pointer dereference was discovered in libxml2, when using xmllint --recover. A maliciously crafted file, when parsed in recovery mode, could cause the application to crash.
Отчет
Recovery mode is not intended for use with untrusted input. Users invoking xmllint --recover may experience a crash, but applications processing documents from possibly malicious sources should not be exposed to this flaw.
