CVE-2019-14878 not yet assigned priority: Debian including 2 source packages (newlib, picolibc), 10 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 10.
In the __d2b function of the newlib libc library, all versions prior to 3.3.0 (see newlib/libc/stdlib/mprec.c), Balloc is used to allocate a big integer, however no check is performed to verify if the allocation succeeded or not. Accessing _x will trigger a null pointer dereference bug in case of a memory allocation failure.
