getaddrinfo(3) failed I'm trying to connect to a webservice using a PHP wrapper (which is using curl under the covers). On my local linux machine running PHP 5.3 it works perfectly.
A stack-based critical buffer overflow was found in the way the libresolv library (glibc) performed dual A/AAAA DNS queries. A remote attacker could crash or, potentially, execute code running the library on Linux. How do I patch and protect my server or workstation against the glibc getaddrinfo on Linux operating system?

Quite a lof systems are potentially vulnerable to this exploit: Red Hat Enterprise Linux 6 & CentOS 6: RHSA-2016:0175-1; Red Hat Enterprise Linux 7 & CentOS 7: RHSA-2016:0176-1; Debian Squeeze, Wheezy, Jessy & Stretch: CVE-2015-7547; Ubuntu 12.04 & 14.04: CVE-2015 getaddrinfo is a library function in the standard C library, not a command line tool. So trying to execute it is not quite the right path to a solution. You can call getaddrinfo from a python shell if you want: getaddrinfo () is specified in POSIX.1-2001 (and RFC 2553), and Microsoft is known for never following a standard it could extend or pervert, so of course it's a totally different function in Windows. The relevant MSDN page says it "provides protocol-independent translation from an ANSI host name to an address."

The freeaddrinfo() function shall free one or more addrinfostructures returned by getaddrinfo(), along with any additional storage associated with those structures. If the ai_nextfield of the structure is not null, the entire list of structures shall be freed. The freeaddrinfo() function shall support the freeing of arbitrary
Function Name: getaddrinfo . Function Signature: socket.getaddrinfo(host, port, family=0, type=0, proto=0, flags=0) Function Overview: If we know a network service by host name like example.org or the IP address of the network service either in form of IPv4 or IPv6 along with the port number of the network service, getaddrinfo() will return a list of tuples containing information about socket 0011000: getaddrinfo() causes SIGSEGV in a multi-threaded program when linked statically: Linux 3.10.0-327.18.2.el7.x86_64 Architecture: x86-64 cat /etc/*release getaddrinfo / inet_ntop example. GitHub Gist: instantly share code, notes, and snippets. Socket applications often need to convert hostnames like google.com to their corresponding ip address. This is done through dns requests. The socket api in linux provides functions like gethostbyname and getaddrinfo that can be used to perform the dns requests and get the ip address. gethostbyname The first method uses the traditional gethostbyname function to
