Description Laura Pardo 2019-01-31 15:29:28 UTC 
A vulnerability was found in elfutils 0.174. An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.c in libelf. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception.

Comment 2 Riccardo Schirone 2019-02-22 15:28:42 UTC 
I'm closing this as NOTABUG and I have requested to reject this CVE to MITRE, because the issue is just caused by ASAN, which tries to detect big allocations.
