Description

An issue was discovered in xmllint (from libxml2) before 2.11.8 and 2.12.x before 2.12.7. Formatting error messages with xmllint --htmlout can result in a buffer over-read in xmlHTMLPrintFileContext in xmllint.c. A flaw was found in the xmllint program distributed by the libxml2 package. A buffer over-read in the xmlHTMLPrintFileContext function in the xmllint.c file may be triggered when a crafted file is processed with the xmllint program using the `--htmlout` command line option, causing an application crash and resulting in a denial of service.
