Zig does not vendor glibc source code however it does make use of `posix_memalign` and can be made to pass an alignment of `1 << 63` to glibc. Its been reported to upstream though I see it unlikely to be a major vulnerability to any zig program. *** Bug 2430077 has been marked as a duplicate of this bug. *** *** Bug 2430075 has been marked as a duplicate of this bug. *** *** Bug 2430074 has been marked as a duplicate of this bug. *** Upstream considers this issue to be neglible for them and only exploitable through misuse of the standard library. |
