Juniper Junos Multiple OpenSSL Vulnerabilities (JSA10629)
Medium Nessus Plugin ID 77000
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionAccording to its self-reported version number, the remote Juniper Junos device is affected by the following vulnerabilities related to OpenSSL :
- An error exists in the ssl3_read_bytes() function that permits data to be injected into other sessions or allows denial of service attacks. Note that this issue is exploitable only if SSL_MODE_RELEASE_BUFFERS is enabled. (CVE-2010-5298)
- An error exists in the do_ssl3_write() function that permits a NULL pointer to be dereferenced, which could allow denial of service attacks. Note that this issue is exploitable only if SSL_MODE_RELEASE_BUFFERS is enabled. (CVE-2014-0198)
- An error exists in the processing of ChangeCipherSpec messages that allows the usage of weak keying material.
This permits simplified man-in-the-middle attacks to be done. (CVE-2014-0224)
- An error exists in the dtls1_get_message_fragment() function related to anonymous ECDH cipher suites. This could allow denial of service attacks. Note that this issue only affects OpenSSL TLS clients. (CVE-2014-3470)
Note that these issues only affects devices with J-Web or the SSL service for JUNOScript enabled.
