A heap-based buffer overflow vulnerability in elfutils might allow remote attackers to execute arbitrary code.
|Package||dev-libs/elfutils on all architectures|
|Affected versions||< 0.159|
|Unaffected versions||>= 0.159|
Elfutils provides a library and utilities to access, modify and analyse ELF objects.
An integer overflow, in the check_section function of dwarf_begin_elf.c, in the libdw library can lead to a heap-based buffer overflow.
A remote attacker could entice a user to open a specially crafted file, possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All elfutils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/elfutils-0.159"
