Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. misc: Fix out-of-bounds array write in tdelete (bug 34506) Allocate the maximum array sizes directly, instead of resizing the arrays as needed. This eliminates alloca usage from the function, and fixes the out-of-bounds accesses. The asserts guard against the bug coming back if the balancing of the tree turns out not to work correctly.
Zig is not affected by this vulnerability. While `zig.spec` declares `Provides: bundled(glibc) = 2.43` to account for embedded headers and ABI symbol metadata, Zig does not bundle or compile the GNU C Library implementation of the affected routine. Specifically: - Zig only ships glibc ABI symbol tables (`abilists`) to generate compile-time dynamic linking stubs (`.so`), generic headers, and minimal C runtime startup objects (`crt1.o`, `elf-init`, `stat` shims). - Zig compiler binaries and generated executables dynamically link against the host/target system's runtime `libc.so.6`. Closing as NOTABUG.
