medium Nessus Plugin ID 126082

Language:

Synopsis

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

Description

zhangyang reports :

The ReadFrame function in the avi.c file uses a variable i_width_bytes, which is obtained directly from the file. It is a signed integer. It does not do a strict check before the memory operation(memmove, memcpy), which may cause a buffer overflow.

Solution

Update the affected package.
