Then, when the loop is entered again and the value is below 0xC0, an out-of-bounds write occurs creating an exploitable condition. There is no verification that the buffer is within bounds after this increment. If this check is true, it goes into the if statement and writes directly to the image buffer. whileĪt location, the compressed image data is read and compared against 0xC0. The error comes in due to the incorrect calculation of the size of the compressed data. The compression scheme is determined via the file header, and by choosing “run length encoding” as the compression, the program writes out of bounds using user-controlled data. The vulnerability arises in parsing the PCX image, specifically dealing with the compression of the image. PCX was a popular image format with early computers, and although it has been replaced by more sophisticated formats, it is still in use and fully supported inside of Canvas Draw. The vulnerable component is in the handling of PCX images. This product has a large user base, and is popular in its specific field. Photoline is an image processing tool used to modify and edit images, as well as other graphic-related material. Tested VersionsĬomputerinsel Photoline 20.53 for OS X Product URLsĨ.8 - CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H CWE An attacker can deliver a PCX image to trigger this vulnerability and gain code execution. A specially crafted PCX image processed via the application can lead to an out-of-bounds write, overwriting arbitrary data. ![]() Saving Earth Britannica Presents Earth’s To-Do List for the 21st Century.A memory corruption vulnerability exists in the PCX-parsing functionality of Computerinsel Photoline 20.53.The new version is a lot faster on large groups of files due to multi threading. 100 Women Britannica celebrates the centennial of the Nineteenth Amendment, highlighting suffragists and history-making politicians.
