CVE-2010-2799

Status: ModifiedMedium (6.8)—

Stack-based buffer overflow in the nestlex function in nestlex.c in Socat 1.5.0.0 through 1.7.1.2 and 2.0.0-b1 through 2.0.0-b3, when bidirectional data relay is enabled, allows context-dependent attackers to execute arbitrary code via long command-line arguments.

CVSS
