2.1-377 | 2013-03-17 17:36:09 -0700
|
||||
|
||||
* Fixing potential leak in DNS error case. (Vlad Grigorescu)
|
||||
|
||||
2.1-375 | 2013-03-17 13:14:26 -0700
|
||||
|
||||
* Add base64 encoding functionality, including new BiFs
|
||||
encode_base64() and encode_base64_custom(). (Bernhard Amann)
|
||||
|
||||
* Replace call to external "openssl" in extract-certs-pem.bro with
|
||||
that encode_base64(). (Bernhard Amann)
|
||||
|
||||
* Adding a test for extract-certs-pem.pem. (Robin Sommer)
|
||||
|
||||
* Renaming Base64Decoder to Base64Converter. (Robin Sommer)
|
||||
|
||||
2.1-366 | 2013-03-17 12:35:59 -0700
|
||||
|
||||
* Correctly handle DNS lookups for software version ranges. (Seth
|
||||
Hall)
|
||||
|
||||
* Improvements to vulnerable software detection. (Seth Hall)
|
||||
|
||||
- Add a DNS based updating method. This needs to be tested
|
||||
still.
|
||||
|
||||
- Vulnerable version ranges are used now instead of only single
|
||||
versions. This can deal with software with multiple stable
|
||||
major versions.
|
||||
|
||||
* Update software version parsing and comparison to account for a
|
||||
third numeric subversion. Also, $addl is now compared numerically
|
||||
if the value is actually numeric. (Seth Hall)
|
||||
|
||||
2.1-361 | 2013-03-13 07:18:22 -0700
|
||||
|
||||
* Add check for truncated link frames. Addresses #962. (Jacob
