In elfutils 0.183, an infinite loop was found in the function handlesymtab in readelf.c .Which allows attackers to cause a denial of service (infinite loop) via crafted file.

In elfutils 0.175, a negative-sized memcpy is attempted in elfcvtnote in libelf/notexlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash).

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=allocatormayreturnnull=1 and running the reproducer, nothing happens."

In elfutils 0.175, there is a buffer over-read in the eblobjectnote function in eblobjnote.c in libebl. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted elf file, as demonstrated by eu-readelf.
