There is an illegal WRITE memory access at common-image.c (function load_image) in libcaca 0.99.beta19 for 4bpp data.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the c10b639c-e51c-11ef-9e76-4ccc6adda413 advisory.

    Sam Hocevar reports:
    Multiple memory leaks and invalid memory accesses:
