An exploitable information leak/denial of service vulnerability exists in the libevm (Ethereum Virtual Machine) `create2` opcode handler of CPP-Ethereum. A specially crafted smart contract code can cause an out-of-bounds read leading to memory disclosure or denial of service. An attacker can create/send malicious a smart contract to trigger this vulnerability.

An issue, also known as DW201703-006, was discovered in libdwarf 2017-03-21. A heap-based buffer over-read in dwarf_formsdata() is due to a failure to check a pointer for being in bounds (in a few places in this function) and a failure in a check in dwarf_attr_list().

An issue, also known as DW201703-001, was discovered in libdwarf 2017-03-21. In dwarf_formsdata() a few data types were not checked for being in bounds, leading to a heap-based buffer over-read.

An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5.

In FreeBSD 12.0-STABLE before r350648, 12.0-RELEASE before 12.0-RELEASE-p9, 11.3-STABLE before r350650, 11.3-RELEASE before 11.3-RELEASE-p2, and 11.2-RELEASE before 11.2-RELEASE-p13, the ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs. A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page and subsequently panic.

An out-of-bounds read when an HTTP/2 connection to a servers sends "DATA" frames with incorrect data content. This leads to a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming RTCP BYE message contains a reason's length, this declared length is not checked against the actual received packet size, potentially resulting in an out-of-bound read access. This issue affects all users that use PJMEDIA and RTCP. A malicious actor can send a RTCP BYE message with an invalid reason length. Users are advised to upgrade as soon as possible. There are no known workarounds.

A programming error exists in a way Randombit Botan cryptographic library version 2.0.1 implements x500 string comparisons which could lead to certificate verification issues and abuse. A specially crafted X509 certificate would need to be delivered to the client or server application in order to trigger this vulnerability.

An issue was discovered in SVG++ (aka svgpp) 1.2.3. After calling the gil::get_color function in Generic Image Library in Boost, the return code is used as an address, leading to an Access Violation because of an out-of-bounds read.

The OLSR parser in tcpdump before 4.9.2 has a buffer over-read in print-olsr.c:olsr_print().

sqclass.cpp in Squirrel through 2.2.5 and 3.x through 3.1 allows an out-of-bounds read (in the core interpreter) that can lead to Code Execution. If a victim executes an attacker-controlled squirrel script, it is possible for the attacker to break out of the squirrel script sandbox even if all dangerous functionality such as File System functions has been disabled. An attacker might abuse this bug to target (for example) Cloud services that allow customization via SquirrelScripts, or distribute malware through video games that embed a Squirrel Engine.

The implementations of streams for bz2 and php://output improperly implemented their readImpl functions, returning -1 consistently. This behavior caused some stream functions, such as stream_get_line, to trigger an out-of-bounds read when operating on such malformed streams. The implementations were updated to return valid values consistently. This affects all supported versions of HHVM (3.30 and 3.27.4 and below).
