A heap-based buffer overflow in TCPTrack might allow a remote attacker to execute arbitrary code.
|Package||net-analyzer/tcptrack on all architectures|
|Affected versions||< 1.4.2|
|Unaffected versions||>= 1.4.2|
TCPTrack is a simple libpcap based program for live TCP connection monitoring.
A heap-based buffer overflow vulnerability exists in TCPTrack’s parsing of command line arguments. This is only a vulnerability in limited scenarios in which TCPTrack is “configured as a handler for other applications.”
A remote attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition with a specially crafted command-line argument.
There is no known workaround at this time.
All TCPTrack users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/tcptrack-1.4.2"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since August 06, 2011. It is likely that your system is already no longer affected by this issue.
