| CVE-2021-32614 | Date: (C)2021-05-27 (M)2023-12-22 |
A flaw was found in dmg2img through 20170502. fill_mishblk() does not check the length of the read buffer, and copy 0xCC bytes from it. The length of the buffer is controlled by an attacker. By providing a length smaller than 0xCC, memcpy reaches out of the malloc'ed bound. This possibly leads to memory layout information leaking in the data. This might be used in a chain of vulnerability in order to reach code execution.
