Out-of-bounds Write

A heap-based buffer overflow issue was discovered in ImageMagick's ReadTIM2ImageData() function in coders/tim2.c. A local attacker could trick the user in opening specially crafted file, triggering an out-of-bounds read error, allowing an application to crash, resulting in a denial of service.Show less

In _PMRCreate of the PowerVR kernel driver, a missing bounds check means it is possible to overwrite heap memory via PhysmemNewRamBackedPMR. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Show less

cpdb-libs provides frontend and backend libraries for the Common Printing Dialog Backends (CPDB) project. In versions 1.0 through 2.0b4, cpdb-libs is vulnerable to buffer overflows via improper use of `scanf(3)`. cpdb-libs uses the `fscanf()` and `scanf()` functions to parse command lines and configuration files, dropping the read string components into fixed-length buffers, but does not limit the length of the strings to be read by `fscanf()` and `scanf()` causing buffer overflows when a string is longer than 1023 characters. A patch for this issue is available at commit f181bd1f14757c2ae0f17cc76dc20421a40f30b7. As all buffers have a length of 1024 characters, the patch limits the maximum string length to be read to 1023 by replacing all occurrences of `%s` with `%1023s` in all calls of the `fscanf()` and `scanf()` functions.Show less
