ruby: entity expansion DoS vulnerability in REXML
lib/rexml/text.rb in the REXML parser in Ruby before 1.9.3-p392 allows remote attackers to cause a denial of service memory consumption and crash via crafted text nodes in an XML document, aka an XML Entity Expansion XEE attack...
ruby: Unsafe use of alloca in rb_str_format()
The rbstrformat function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2 allows context-dependent attackers to trigger memory corruption via unspecified vectors related to alloca, a different issue than CVE-2008-2662,...
ruby: Buffer overrun in String-to-Float conversion
A buffer overrun vulnerability was found in Ruby. The issue occurs in a conversion algorithm from a String to a Float that causes process termination due to a segmentation fault, but under limited circumstances. This flaw may cause an illegal memory read...
ruby: Arbitrary memory address read vulnerability with Regex search
A flaw was found in Ruby. If attacker-supplied data is provided to the Ruby regex compiler, it is possible to extract arbitrary heap data relative to the start of the text, including pointers and sensitive strings...
ruby: Cookie prefix spoofing in CGI::Cookie.parse
A flaw was found in Ruby. RubyGems cgi gem could allow a remote attacker to conduct spoofing attacks caused by the mishandling of security prefixes in cookie names in the CGI::Cookie.parse function. By sending a specially-crafted request, an attacker could perform cookie prefix spoofing attacks...
ruby: Unintentional directory traversal by poisoned NULL byte in Dir
It was found that the methods from the Dir class did not properly handle strings containing the NULL byte. An attacker, able to inject NULL bytes in a path, could possibly trigger an unspecified behavior of the ruby script...
ruby: SMTP command injection via CRLF sequences in RCPT TO or MAIL FROM commands in Net::SMTP
A SMTP command injection flaw was found in the way Ruby's Net::SMTP module handled CRLF sequences in certain SMTP commands. An attacker could potentially use this flaw to inject SMTP commands in a SMTP session in order to facilitate phishing attacks or spam campaigns...
ruby: FTP PASV command response can cause Net::FTP to connect to arbitrary host
Ruby's Net::FTP module trusted the IP address included in the FTP server's response to the PASV command. A malicious FTP server could use this to make Ruby applications using the Net::FTP module to connect to arbitrary hosts and use this to perform port scanning or information extraction from...
ruby: integer overflow in rb_ary_splice/update/replace() - beg + rlen
Integer overflow in the 1 rbarysplice function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2; and 2 the rbaryreplace function in 1.6.x allows context-dependent attackers to trigger memory corruption, aka the "beg +...
ruby: Integer overflows in rb_str_buf_append()
Multiple integer overflows in the rbstrbufappend function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2 allow context-dependent attackers to execute arbitrary code or cause a denial of service via unknown vectors that...
ruby: REXML billion laughs attack via parameter entity expansion
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...
ruby: multiple insufficient safe mode restrictions
Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not properly restrict access to critical variables and methods at various safe levels, which allows context-dependent attackers to bypass intended access restrictions via 1 untracevar, 2...
ruby: Properly initialize the random number generator when forking new process
The SecureRandom.randombytes function in lib/securerandom.rb in Ruby before 1.8.7-p352 and 1.9.x before 1.9.2-p290 relies on PID values for initialization, which makes it easier for context-dependent attackers to predict the result string by leveraging knowledge of random strings obtained in an...
ruby: Properly initialize the random number generator when forking new process
Ruby before 1.8.6-p114 does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process, a related issue to CVE-2003-0900...
ruby: Unsafe parsing of long strings via decode_www_form_component method
The URI.decodewwwformcomponent method in Ruby before 1.9.2-p330 allows remote attackers to cause a denial of service catastrophic regular expression backtracking, resource consumption, or application crash via a crafted string...
