Detail

Synopsis

A stack-based buffer overflow was found in file, possibly resulting in the execution of arbitrary code.

Background

file is a utility that guesses a file format by scanning binary data for patterns.

Description

An issue discovered in file allows attackers to write 20 bytes to the stack buffer via a specially crafted .notes section.

Impact

A remote attacker, by using a specially crafted .notes section in an ELF binary, could execute arbitrary code or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All file users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/file-5.32"
