Integer Overflow or Wraparound

An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls.Show less

miniSphere version 5.2.9 and earlier contains a Integer Overflow vulnerability in layer_resize() function in map_engine.c that can result in remote denial of service. This attack appear to be exploitable via the victim must load a specially-crafted map which calls SetLayerSize in its entry script. This vulnerability appears to have been fixed in 5.0.3, 5.1.5, 5.2.10 and later.Show less

In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), transfer-encoding chunks are handled poorly. The chunk length parsing was vulnerable to an integer overflow. Thus a large chunk size could be interpreted as a smaller chunk size and content sent as chunk body could be interpreted as a pipelined request. If Jetty was deployed behind an intermediary that imposed some authorization and that intermediary allowed arbitrarily large chunks to be passed on unchanged, then this flaw could be used to bypass the authorization imposed by the intermediary as the fake pipelined request would not be interpreted by the intermediary as a request.Show less

The sell function of a smart contract implementation for SEC, a tradable Ethereum ERC20 token, allows a potential trap that could be used to cause financial damage to the seller, because of overflow of the multiplication of its argument amount and a manipulable variable sellPrice, aka the "tradeTrap" issue.Show less

The sell function of a smart contract implementation for Target Coin (TGT), a tradable Ethereum ERC20 token, allows a potential trap that could be used to cause financial damage to the seller, because of overflow of the multiplication of its argument amount and a manipulable variable sellPrice, aka the "tradeTrap" issue.Show less

The sell function of a smart contract implementation for Substratum (SUB), a tradable Ethereum ERC20 token, allows a potential trap that could be used to cause financial damage to the seller, because of overflow of the multiplication of its argument amount and a manipulable variable sellPrice, aka the "tradeTrap" issue.Show less

The sell function of a smart contract implementation for Internet Node Token (INT), a tradable Ethereum ERC20 token, allows a potential trap that could be used to cause financial damage to the seller, because of overflow of the multiplication of its argument amount and a manipulable variable sellPrice, aka the "tradeTrap" issue.Show less

The sell function of a smart contract implementation for SwftCoin (SWFTC), a tradable Ethereum ERC20 token, allows a potential trap that could be used to cause financial damage to the seller, because of overflow of the multiplication of its argument amount and a manipulable variable sellPrice, aka the "tradeTrap" issue.Show less

The buy function of a smart contract implementation for Gold Reward (GRX), an Ethereum ERC20 token, allows a potential trap that could be used to cause financial damage to the buyer because of overflow of the multiplication of its argument amount and a manipulable variable buyPrice, aka the "tradeTrap" issue.Show less

qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.Show less

The getImageData function in the ImageBufferCairo class in WebCore/platform/graphics/cairo/ImageBufferCairo.cpp in WebKit, as used in WebKitGTK+ prior to version 2.20.3 and WPE WebKit prior to version 2.20.1, is vulnerable to a heap-based buffer overflow triggered by an integer overflow, which could be abused by crafted HTML content.Show less

Improper input validation together with an integer overflow in the EAP-TLS protocol implementation in PPPD may cause a crash, information disclosure, or authentication bypass. This implementation is distributed as a patch for PPPD 0.91, and includes the affected eap.c and eap-tls.c files. Configurations that use the `refuse-app` option are unaffected.Show less

In the function wmi_set_ie(), the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the 'ie_len' argument can cause a buffer overflow in all Android releases from CAF (Android for MSM, Firefox OS for MSM, QRD Android) using the Linux Kernel.Show less
