4 | Subject: [PATCH] Fix memory leak in xmlSchemaValidateStream | ||
5 | |||
6 | When ctxt->schema is NULL, xmlSchemaSAXPlug->xmlSchemaPreRun | ||
7 | alloc a new schema for ctxt->schema and set vctxt->xsiAssemble | ||
8 | to 1. Then xmlSchemaVStart->xmlSchemaPreRun initialize | ||
9 | vctxt->xsiAssemble to 0 again which cause the alloced schema | ||
10 | can not be freed anymore. | ||
11 | |||
12 | Found with libFuzzer. | ||
