Ruslan Valiyev libiberty: fix resource exhaustion in rust demangler (PR demangler/106641) 4mo ago

libiberty: fix resource exhaustion in rust demangler (PR demangler/106641) demangle_binder() parses the bound_lifetimes count as a base-62 integer with no upper bound. A crafted symbol can encode a huge lifetime count in very few bytes, causing OOM or CPU hang. Cap bound_lifetimes at 1024 and check rdm->errored in the loop so it bails out early on errors during iteration. libiberty/ChangeLog: PR demangler/106641 * rust-demangle.c (demangle_binder): Reject bound_lifetimes above 1024 to prevent resource exhaustion from crafted symbols. Add rdm->errored check in the loop condition. * testsuite/rust-demangle-expected: Add regression test. Signed-off-by: Ruslan Valiyev <linuxoid@gmail.com>

d-demangle-expected

libiberty: Invoke D demangler when --format=auto Investigating GDB PR d/31580 showed that the libiberty demangler doesn't automatically demangle D mangled names. However, I think it should -- like C++ and Rust (new-style), D mangled names are readily distinguished by the leading "_D", and so the likelihood of confusion is low. The other non-"auto" cases in this code are Ada (where the encoded form could more easily be confused by ordinary programs) and Java (which is long gone, but which also shared the C++ mangling and thus was just an output style preference). This patch also fixed another GDB bug, though of course that part won't apply to the GCC repository. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=31580 Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=30276 libiberty * cplus-dem.c (cplus_demangle): Try the D demangler with "auto" format. * testsuite/d-demangle-expected: Add --format=auto test.
