The remote FreeBSD host is missing a security-related update.
From Gentoo advisory GLSA 200410-01 :
sharutils contains two buffer overflows. Ulf Harnhammar discovered a
buffer overflow in shar.c, where the length of data returned by the wc
command is not checked. Florian Schilhabel discovered another buffer
overflow in unshar.c.
An attacker could exploit these vulnerabilities to execute arbitrary
code as the user running one of the sharutils programs.
