FreeBSD : zoo -- stack based buffer overflow (d9307a41-c4d7-11da-b2fb-000e0c2e438a)

Medium Nessus Plugin ID 21518


The remote FreeBSD host is missing a security-related update.


Jean-Sebastien Guay-Leroux report a vulnerability within the zoo archiver. The vulnerability which is present in the fullpath() function (from the misc.c file) is caused by improper checking of user supplied data. The data returned to the buffer can be up to 512 bytes, while the buffer is created to hold 256 bytes. This could result in a buffer overflow which could allow remote code execution.


Update the affected package.
