CVE-ID : CVE-2018-18310 CVE-2018-18520 CVE-2018-18521
Package : elfutils
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-785
The package elfutils before version 0.175-1 is vulnerable to denial of
service.
Upgrade to 0.175-1.
The problems have been fixed upstream in version 0.175.
None.
An invalid memory address dereference was discovered in
dwfl_segment_report_module.c in libdwfl in elfutils through v0.174. The
vulnerability allows attackers to cause a denial of service
(application crash) with a crafted ELF file.
An Invalid Memory Address Dereference exists in the function elf_end in
libelf in elfutils through v0.174. Although eu-size is intended to
support ar files inside ar files, handle_ar in size.c closes the outer
ar file before handling all inner entries. The vulnerability allows
attackers to cause a denial of service (application crash) with a
crafted ELF file.
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in
arlib.c in elfutils 0.174 allow remote attackers to cause a denial of
service (application crash) with a crafted ELF file, as demonstrated by
eu-ranlib, because a zero sh_entsize is mishandled.
An attacker can crash an application using one of the elfutils
libraries to parse files via a crafted ELF file.
