Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2019-14876 unimportant priority: Debian including 2 source packages (newlib, picolibc), 10 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 5, resolved 5.
In the __lshift 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. The access to b1 will trigger a null pointer dereference bug in case of a memory allocation failure.
