The problems have been fixed upstream but no release is available yet.
- CVE-2016-1234 (arbitrary code execution)
It was found that glob implementation in glibc does not correctly
handle overlong names in struct dirent buffers when GLOB_ALTDIRFUNC is
used, causing a large stack-based buffer overflow with controlled
length and content.
- CVE-2016-3706 (denial of service)
A stack (frame) overflow flaw, which could lead to a denial of service
(application crash), was found in the way glibc's getaddrinfo()
function processed certain requests when called with AF_INET or
A remote attacker is able to perform a denial of service attack via a
vulnerability in the getaddrinfo() function.
Furthermore a local attacker may be able to execute arbitrary code via a
buffer overflow when GLOB_ALTDIRFUNC is used.
