Successful exploitation could lead to information disclosure. Published: Novem10:29:00 PM -0500Īdobe Photoshop CC versions 19.1.6 and earlier have an out-of-bounds read vulnerability. There is an illegal address access at asm/preproc.c (function: is_mmacro) in Netwide Assembler (NASM) 2.14rc16 that will cause a denial of service (out-of-bounds array access) because a certain conversion can result in a negative integer. An attacker must convince a victim to open a specially crafted document in order to trigger this vulnerability. This can allow an attacker to corrupt memory, which can result in code execution under the context of the application. Published: Decem9:29:00 AM -0500Īn exploitable out-of-bounds write vulnerability exists in the PNG implementation of Atlantis Word Processor, version 3.2.7.2. Published: Decem4:29:00 AM -0500Īn issue has been found in PowerDNS Recursor before version 4.1.8 where a remote attacker sending a DNS query can trigger an out-of-bounds memory read while computing the hash of the query for a packet cache lookup, possibly leading to a crash. The function WavpackVerifySingleBlock in open_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (out-of-bounds read and application crash) via a crafted WavPack Lossless Audio file, as demonstrated by wvunpack. 117 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. Show source file for each instruction displays the source file name that corresponds to each assembly instruction.įor more information about assembly debugging and related commands and a full explanation of the assembly display, see Debugging in Assembly Mode.A nullptr dereference in WebAssembly in Google Chrome prior to. Show source line for each instruction displays the source line number that corresponds to each assembly instruction. This command enables you to find all of the instructions that were assembled from the current source line. If code has been optimized, these assembly instructions might not be consecutive. Often, a single source line will correspond to multiple assembly instructions. Highlight instructions from the current source line causes all of the instructions that correspond to the current source line to be highlighted. If this command is cleared, the current line will appear at the top of the Disassembly window, which saves time because reverse-direction disassembly can be time-consuming. Go to current address opens the Source window with the source file that corresponds to the selected line in the Disassembly window and highlights this line.ĭisassemble before current instruction causes the current line to be placed in the middle of the Disassembly window. The following list describes some of the menu commands: To access the menu, select and hold (or right-click) the title bar or select the icon that appears near the upper-right corner of the window ( ). The Disassembly window has a toolbar that contains two buttons and a shortcut menu with additional commands. If you use these keys to move off of the page, a new page will appear. By pressing the RIGHT ARROW, LEFT ARROW, UP ARROW, and DOWN ARROW keys, you can navigate within the window. These commands display disassembled code from the preceding or following sections of memory, respectively. To see other sections of memory, select the Previous or Next buttons or press the PAGE UP or PAGE DOWN keys. (You can press ENTER after typing the address, but you do not have to.) The Disassembly window displays code before you have completed the address you can disregard this code. To disassemble a different section of memory, in the Offset box, type the address of the memory you want to disassemble. In the Disassembly window, you can do the following: The resulting code is displayed in the Disassembly window. The debugger takes a section of memory, interprets it as binary machine instructions, and then disassembles it to produce an assembly-language version of the machine instructions. The following screen shot shows an example of a Disassembly window. ALT+SHIFT+7 will close the Disassembly Window.) (You can also press ALT+7 or select the Disassembly button ( ) on the toolbar. To open or switch to the Disassembly window, choose Dissasembly from the View menu. You can view assembly code by entering the one of the u, ub, uu (Unassemble) commands in the Debugger Command window. In WinDbg, you can view assembly code by entering commands or by using the Disassembly window.
