Description

An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.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 ASAN_OPTIONS=allocator_may_return_null=1 and running the reproducer, nothing happens."

• CWE-770Allocation of Resources Without Limits or ThrottlingThe product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
