- -------------------------------------------------------------------------
Package : ruby1.9.1
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2013-1821 CVE-2013-4073
Debian Bug : 702525 714543
Several vulnerabilities have been discovered in the interpreter for
the Ruby language, which may lead to denial of service and other
security problems. The Common Vulnerabilities and Exposures project
identifies the following problems:
CVE-2013-1821
Ben Murphy discovered that unrestricted entity expansion in REXML
can lead to a Denial of Service by consuming all host memory.
CVE-2013-4073
William (B.J.) Snow Orvis discovered a vulnerability in the hostname
checking in Ruby's SSL client that could allow man-in-the-middle
attackers to spoof SSL servers via valid certificate issued by a
trusted certification authority.
For the oldstable distribution (squeeze), these problems have been fixed in
version 1.9.2.0-2+deb6u1.
For the stable distribution (wheezy), these problems have been fixed in
version 1.9.3.194-8.1+deb7u1.
For the unstable distribution (sid), these problems have been fixed in
version 1.9.3.194-8.2.
We recommend that you upgrade your ruby1.9.1 packages.

NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-1821 and CVE-2014-8080.(CVE-2014-8090)\n\n - Algorithmic complexity vulnerability in Gem::Version::VERSION_PATTERN in lib/rubygems/version.rb in RubyGems before 1.8.23.1, 1.8.24 through 1.8.25, 2.0.x before 2.0.8, and 2.1.x before 2.1.0, as used in Ruby 1.9.0 through 2.0.0p247, allows remote attackers to cause a denial of service (CPU consumption) via a crafted gem version that triggers a large amount of backtracking in a regular expression.(CVE-2013-4287)\n\n - The REXML parser in Ruby 1.9.x before 1.9.3-p550, 2.0.x before 2.0.0-p594, and 2.1.x before 2.1.4 allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document, aka an XML Entity Expansion (XEE) attack.(CVE-2014-8080)\n\n - The OpenSSL::SSL.verify_certificate_identity function in lib/openssl/ssl.rb in Ruby 1.8 before 1.8.7-p374, 1.9 before 1.9.3-p448, and 2.0 before 2.0.0-p247 does not properly handle a '\\\\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.(CVE-2013-4073)\n\n - The rb_get_path_check function in file.c in Ruby 1.9.3 before patchlevel 286 and Ruby 2.0.0 before r37163 allows context-dependent attackers to create files in unexpected locations or with unexpected names via a NUL byte in a file path.(CVE-2012-4522)\n\n - (1) DL and (2) Fiddle in Ruby 1.9 before 1.9.3 patchlevel 426, and 2.0 before 2.0.0 patchlevel 195, do not perform taint checking for native functions, which allows context-dependent attackers to bypass intended $SAFE level restrictions.(CVE-2013-2065)\n\n - Algorithmic complexity vulnerability in Gem::Version::ANCHORED_VERSION_PATTERN in lib/rubygems/version.rb in RubyGems before 1.8.23.2, 1.8.24 through 1.8.26, 2.0.x before 2.0.10, and 2.1.x before 2.1.5, as used in Ruby 1.9.0 through 2.0.0p247, allows remote attackers to cause a denial of service (CPU consumption) via a crafted gem version that triggers a large amount of backtracking in a regular expression. NOTE: this issue is due to an incomplete fix for CVE-2013-4287.(CVE-2013-4363)\n\n - Ruby (aka CRuby) 1.9 before 1.9.3-p327 and 2.0 before r37575 computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against a variant of the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4815.(CVE-2012-5371)\n\n - Off-by-one error in the encodes function in pack.c in Ruby 1.9.3 and earlier, and 2.x through 2.1.2, when using certain format string specifiers, allows context-dependent attackers to cause a denial of service (segmentation fault) via vectors that trigger a stack-based buffer overflow.(CVE-2014-4975)\n\n - Heap-based buffer overflow in Ruby 1.8, 1.9 before 1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0 preview2, and trunk before revision 43780 allows context-dependent attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a string that is converted to a floating point value, as demonstrated using (1) the to_f method or (2) JSON.parse.(CVE-2013-4164)\n\n - It was found that the methods from the Dir class did not properly handle strings containing the NULL byte.\n An attacker, able to inject NULL bytes in a path, could possibly trigger an unspecified behavior of the ruby script.(CVE-2018-8780)\n\n - Ruby 1.9.3 before patchlevel 286 and 2.0 before revision r37068 allows context-dependent attackers to bypass safe-level restrictions and modify untainted strings via the (1) exc_to_s or (2) name_err_to_s API function, which marks the string as tainted, a different vulnerability than CVE-2012-4466. NOTE: this issue might exist because of a CVE-2011-1005 regression.(CVE-2012-4464)\n\n - An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations.(CVE-2018-16395)\n\n - An issue was discovered in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3.
