The ELF parser in file 5.08 through 5.21 allows remote attackers to cause a denial of service via a large number of notes. (CVE-2014-9620)
The ELF parser (readelf.c) in file before 5.21 allows remote attackers to cause a denial of service (CPU consumption or crash) via a large number of (1) program or (2) section headers or (3) invalid capabilities. (CVE-2014-8116)
It was reported that a malformed elf file can cause file urility to access invalid memory. (CVE-2014-9653)
The ELF parser in file 5.16 through 5.21 allows remote attackers to cause a denial of service via a long string. (CVE-2014-9621)
softmagic.c in file before 5.21 does not properly limit recursion, which allows remote attackers to cause a denial of service (CPU consumption or crash) via unspecified vectors. (CVE-2014-8117)
