Code execution via CR2 parser out-of-bounds write
Published Feb 9, 2021 · Updated Aug 4, 2024
Out-of-bounds write in CR2 parsing in Foxit Studio Photo 3.6.6.922 allows remote attackers to execute code through a crafted image file. The CR2 parser insufficiently validates user-supplied data before writing it, allowing a write past the end of an allocated structure. Exploitation requires the target to visit a malicious page or open a malicious file, and resulting code runs in the current process.
