The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200606-15 (Asterisk: IAX2 video frame buffer overflow)

Asterisk fails to properly check the length of truncated video frames in the IAX2 channel driver which results in a buffer overflow.
Impact :

An attacker could exploit this vulnerability by sending a specially crafted IAX2 video stream resulting in the execution of arbitrary code with the permissions of the user running Asterisk.
Workaround :

Disable public IAX2 support.


All Asterisk users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/asterisk-1.0.11_p1'
