* SECURITY UPDATE: Out-of-bounds read in the D-Bus introspection XML parser
- debian/patches/CVE-2026-58016.patch: fix the inverted
nesting
check in parser_start_element() in gio/gdbusintrospection.c, which
accepted a element inside ///
and left the parser reading X->pdata[X->len - 1] with len == 0
- CVE-2026-58016
* debian/rules: add arm to the qemu-buildd architecture list, raising
test_timeout_multiplier from 5 to 20 on armel. Debian builds armel on real
ARM hardware and so left it in the "slow architecture" tier, but this
platform builds it under emulation, where the +slow suite exceeds the
resulting 900s cap non-deterministically (gvariant 435s/262s/timeout,
642026 488s/501s/timeout across three runs of the same tree). No test is
skipped and no other architecture is affected: arm64 and amd64 do not
match the arm filter word.
