Summary
[none]
Details

An attempted excessive memory allocation was discovered in the function readlongnames in elfbegin.c in libelf in elfutils 0.174. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception. NOTE: The maintainers believe this is not a real issue, but instead a "warning caused by ASAN because the allocation is big. By setting ASANOPTIONS=allocatormayreturn_null=1 and running the reproducer, nothing happens."
