DLA 1358-1: ruby1.9.1 security update

Package : ruby1.9.1
Version : 1.9.3.194-8.1+deb7u8
CVE ID : CVE-2017-17742 CVE-2018-6914 CVE-2018-8777 CVE-2018-8778
CVE-2018-8779 CVE-2018-8780 CVE-2018-1000075 CVE-2018-1000076
CVE-2018-1000077 CVE-2018-1000078

Multiple vulnerabilities were found in the interpreter for the Ruby
language. The Common Vulnerabilities and Exposures project identifies the
following issues:

CVE-2017-17742

Aaron Patterson reported that WEBrick bundled with Ruby was vulnerable to
an HTTP response splitting vulnerability. It was possible for an attacker
to inject fake HTTP responses if a script accepted an external input and
output it without modifications.

CVE-2018-6914

ooooooo_q discovered a directory traversal vulnerability in the
Dir.mktmpdir method in the tmpdir library. It made it possible for
attackers to create arbitrary directories or files via a .. (dot dot) in
the prefix argument.

CVE-2018-8777

Eric Wong reported an out-of-memory DoS vulnerability related to a large
request in WEBrick bundled with Ruby.

CVE-2018-8778

aerodudrizzt found a buffer under-read vulnerability in the Ruby
String#unpack method. If a big number was passed with the specifier @,
the number was treated as a negative value, and an out-of-buffer read
occurred. Attackers could read data on heaps if an script accepts an
external input as the argument of String#unpack.

CVE-2018-8779

ooooooo_q reported that the UNIXServer.open and UNIXSocket.open
methods of the socket library bundled with Ruby did not check for NUL
bytes in the path argument. The lack of check made the methods
vulnerable to unintentional socket creation and unintentional socket
access.

CVE-2018-8780

ooooooo_q discovered an unintentional directory traversal in
some methods in Dir, by the lack of checking for NUL bytes in their
parameter.

CVE-2018-1000075

A negative size vulnerability in ruby gem package tar header that could
cause an infinite loop.

CVE-2018-1000076

Ruby gems package improperly verifies cryptographic signatures. A mis-signed
gem could be installed if the tarball contains multiple gem signatures.

CVE-2018-1000077

An improper input validation vulnerability in ruby gems specification
homepage attribute could allow malicious gem to set an invalid homepage
URL.

CVE-2018-1000078

Cross Site Scripting (XSS) vulnerability in gem server display of homepage
attribute

For Debian 7 "Wheezy", these problems have been fixed in version
1.9.3.194-8.1+deb7u8.

We recommend that you upgrade your ruby1.9.1 packages.
