- gitlab has a tendency to change checksum of patches due to metadata changes - switch to including the patches in the tree directly instead of using PATCH_FILES PR: 251040 Submitted by: daniel.engberg.lists@pyret.net Reported by: David Armstrong <bink19th@pm.me>

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