-Subject: [PATCH] Bug 4843 pt1: ext_edirectory_userip_acl refactoring for GCC-8
- (#204)
-
-Proposed changes to this helper to fix strcat / strncat buffer
-overread / overflow issues.
-
-The approach takes three parts:
-
-* adds a makeHexString function to replace many for-loops
-  catenating bits of strings together with hex conversion into a
-  second buffer. Replacing with a snprintf() and buffer overflow
-  handling.
-
-* a copy of Ip::Address::lookupHostIp to convert the input
-  string into IP address binary format, then generate the hex
-  string using the above new hex function instead of looped
-  sub-string concatenations across several buffers.
-  This removes all the "00" and "0000" strncat() calls and
-  allows far simpler code even with added buffer overflow
-  handling.
-
-* replace multiple string part concatenations with a few simpler
-  calls to snprintf() for all the search_ip buffer constructions.
-  Adding buffer overflow handling as needed for the new calls.

-Subject: [PATCH] smblib: fix buffer over-read
-
-When parsing SMB LanManager packets with invalid protocol ID and the
-default set of Squid supported protocols. It may access memory outside
-the buffer storing protocol names.
-
-smblib is only used by already deprecated helpers which are deprecated
-due to far more significant NTLM protocol issues. It will also only
-result in packets being rejected later with invalid protocol names. So
-this is a minor bug rather than a vulnerability.
-
- Detected by Coverity Scan. Issue 1256165
