CVE-2011-4838

CVE-2011-4838 affects JRuby prior to 1.6.5.1, where hash values can be triggered to collide predictably, enabling context-dependent attackers to cause a denial of service (CPU consumption) via crafted inputs in applications that use hash tables. The vulnerability is documented across multiple sou...

CVE-2011-4838

JRuby before 1.6.5.1 computes hash values without 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...

Multiple implementations -- DoS via hash algorithm collision

oCERT reports: A variety of programming languages suffer from a denial-of-service DoS condition against storage functions of key/value pairs in hash data structures, the condition can be leveraged by exploiting predictable collisions in the underlying hashing algorithms. The issue finds particula...

JRuby before 1.6.5.1 computes hash values without 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...

jruby: XSS in the regular expression engine when processing invalid UTF-8 byte sequences

The regular expression engine in JRuby before 1.4.1, when $KCODE is set to 'u', does not properly handle characters immediately after a UTF-8 character, which allows remote attackers to conduct cross-site scripting XSS attacks via a crafted string...

The regular expression engine in JRuby before 1.4.1, when $KCODE is set to 'u', does not properly handle characters immediately after a UTF-8 character, which allows remote attackers to conduct cross-site scripting XSS attacks via a crafted string...

jruby-openssl Gem for JRuby fails to do proper certificate validation

A security problem involving peer certificate verification was found where failed verification silently did nothing, making affected applications vulnerable to attackers. Attackers could lead a client application to believe that a secure connection to a rogue SSL server is legitimate. Attackers...
