Integer Overflow or Wraparound

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

An issue was discovered in a smart contract implementation for STeX White List (STE(WL)), an Ethereum token. The contract has an integer overflow. If the owner sets the value of amount to a large number then the "amount * 1000000000000000" will cause an integer overflow in withdrawToFounders().Show less

An issue was discovered in a smart contract implementation for EUC (EUC), an Ethereum token. The contract has an integer overflow. If the owner sets the value of buyPrice to a large number in setPrices() then the "msg.value * buyPrice" will cause an integer overflow in the fallback function.Show less

An issue was discovered in a smart contract implementation for SingaporeCoinOrigin (SCO), an Ethereum token. The contract has an integer overflow. If the owner sets the value of sellPrice to a large number in setPrices() then the "amount * sellPrice" will cause an integer overflow in sell().Show less

An issue was discovered in a smart contract implementation for MKCB, an Ethereum token. If the owner sets the value of sellPrice to a large number in setPrices() then the "amount * sellPrice" will cause an integer overflow in sell().Show less
