Visit http://www.mitel.com/security-advisories for more details.
MiCollab AWV has been confirmed as being affected by a DNS libresolv vulnerability in glibc (CVE-2015-7547).
Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C
Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute
arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or
AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module.
