FreeBSD : sharutils -- buffer overflows (26c9e8c6-1c99-11d9-814e-0001020eed82)

High Nessus Plugin ID 36869


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.


Update the affected package.
