Subject: [PATCH] Fix security framework bypass
|
||||
|
||||
xsltCheckRead and xsltCheckWrite return -1 in case of error but callers
|
||||
don't check for this condition and allow access. With a specially
|
||||
crafted URL, xsltCheckRead could be tricked into returning an error
|
||||
because of a supposedly invalid URL that would still be loaded
|
||||
succesfully later on.
|
||||
|
||||
Fixes #12.
|
||||
|
||||
Thanks to Felix Wilhelm for the report.

||||
The RVTs referenced from function results must not be blindly registered
|
||||
as local, as they might be part of variables from an outer scope. Remove
|
||||
LOCAL/VARIABLE distinction for RVTs. Don't register as local RVT
|
||||
unconditionally when reflagging as LOCAL. Instead, register function
|
||||
result RVTs from inner variables as local RVTs when they're released in
|
||||
xsltFreeStackElem. Keep local function result RVTs xsltReleaseLocalRVTs
|
||||
instead of reregistering.
|
||||
|
||||
Closes: https://gitlab.gnome.org/GNOME/libxslt/issues/2
|
||||
|
||||
Thanks to Daniel Mendler and Martin Gieseking for the reports.
