Detail

Synopsis

A buffer overflow in NUT might allow remote attackers to execute arbitrary code.

Background

Network UPS Tools (NUT) provide support for power devices.

Description

An error in the addchar() function in parseconf.c may cause a buffer overflow.

Impact

A remote attacker could send a specially crafted string to upsd, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All NUT users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-power/nut-2.6.3"
