jhead is vulnerable to Buffer Overflows. The library is vulnerable to Buffer Overflows via shellescape(), jhead.c, jhead. jhead
copies strings to a stack buffer when it detects a &i; or &o.; However, jhead does not check the boundary of the stack buffer. As a result, there will be a stack buffer overflow problem when multiple &i;
or &o;
are given.
