Description Dhananjay Arunesh 2019-04-10 09:05:05 UTC

When processing subtitles format media file, KMPlayer version 2018.12.24.14 or lower doesn't check object size correctly, which leads to integer underflow then to memory out-of-bound read/write. An attacker can exploit this issue by enticing an unsuspecting user to open a malicious file.
