TPTEST: Arbitrary code execution

Background

TPTEST is a tool to measure the speed of a user’s Internet connection.

Description

The GetStatsFromLine() function in TPTEST is vulnerable to buffer overflows from STATS lines with long email and pwd fields.

Impact

A remote attacker could send a specially-crafted STATS line, possibly resulting in arbitrary code execution or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All TPTEST users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-analyzer/tptest-3.1.7-r2"
