Libntlm through 1.5 relies on a fixed buffer size for tSmbNtlmAuthRequest, tSmbNtlmAuthChallenge, and tSmbNtlmAuthResponse read and write operations, as demonstrated by a stack-based buffer over-read in buildSmbNtlmAuthRequest in smbutil.c for a crafted NTLM request.

An issue was discovered in Adobe Flash Player 27.0.0.183 and earlier versions. This vulnerability occurs as a result of a computation that reads data that is past the end of the target buffer due to an integer overflow; the computation is part of the abstraction that creates an arbitrarily sized transparent or opaque bitmap image. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.

tcpdump 4.9.0 has a heap-based buffer over-read in the lldp_print function in print-lldp.c, related to util-print.c.

An issue was discovered in Suricata 4.1.4. By sending multiple IPv4 packets that have invalid IPv4Options, the function IPV4OptValidateTimestamp in decode-ipv4.c tries to access a memory region that is not allocated. There is a check for o->len < 5 (corresponding to 2 bytes of header and 3 bytes of data). Then, "flag = *(o->data + 3)" places one beyond the 3 bytes, because the code should have been "flag = *(o->data + 1)" instead.

The getNodeSize function in ext/rtree/rtree.c in SQLite through 3.19.3, as used in GDAL and other products, mishandles undersized RTree blobs in a crafted database, leading to a heap-based buffer over-read or possibly unspecified other impact.

Creolabs Gravity Version: 1.0 Heap Overflow Potential Code Execution. By creating a large loop whiling pushing data to a buffer, we can break out of the bounds checking of that buffer. When list.join is called on the data it will read past a buffer resulting in a Heap-Buffer-Overflow.
