Integer Overflow or Wraparound

Integer overflow in international date handling in International Components for Unicode (ICU) for C/C++ before 60.1, as used in V8 in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.Show less

Godot Engine version All versions prior to 2.1.5, all 3.0 versions prior to 3.0.6. contains a Signed/unsigned comparison, wrong buffer size chackes, integer overflow, missing padding initialization vulnerability in (De)Serialization functions (core/io/marshalls.cpp) that can result in DoS (packet of death), possible leak of uninitialized memory. This attack appear to be exploitable via A malformed packet is received over the network by a Godot application that uses built-in serialization (e.g. game server, or game client). Could be triggered by multiplayer opponent. This vulnerability appears to have been fixed in 2.1.5, 3.0.6, master branch after commit feaf03421dda0213382b51aff07bd5a96b29487b.Show less

An integer overflow in the distributeBTR function of a smart contract implementation for Bitcoin Red (BTCR), an Ethereum ERC20 token, allows the owner to accomplish an unauthorized increase of digital assets by providing a large address[] array, as exploited in the wild in May 2018, aka the "ownerUnderflow" issue.Show less

An issue was discovered in wifipcap/wifipcap.cpp in TCPFLOW through 1.5.0-alpha. There is an integer overflow in the function handle_prism during caplen processing. If the caplen is less than 144, one can cause an integer overflow in the function handle_80211, which will result in an out-of-bounds read and may allow access to sensitive memory (or a denial of service).Show less

Certain input files may trigger an integer overflow in ttembed input file processing. This overflow could potentially lead to corruption of the input file due to a lack of checking return codes of fgetc/fputc function calls.Show less

PHP 7.x through 7.1.5 allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a long string because of an Integer overflow in mysqli_real_escape_string.Show less

The URL percent-encoding decode function in libcurl before 7.51.0 is called `curl_easy_unescape`. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get either just truncated or both truncated and turned negative. That could then lead to libcurl writing outside of its heap based buffer.Show less

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit PhantomPDF Phantom PDF 9.1.5096. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of PDF documents. When parsing shading patterns, the process does not properly validate user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-6223.Show less

In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when using the RXRPC keys incorrectly assumes the size of a field. This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. This could possibly lead to memory corruption and possible privilege escalation.Show less

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the ASN.1 BER dissector could crash. This was addressed in epan/dissectors/packet-ber.c by ensuring that length values do not exceed the maximum signed integer.Show less

The CHECK macro in mrbgems/mruby-sprintf/src/sprintf.c in mruby 1.4.1 contains a signed integer overflow, possibly leading to out-of-bounds memory access because the mrb_str_resize function in string.c does not check for a negative length.Show less
