Last modified

CVE-2023-52168 is a high-severity vulnerability rated 8.4/10 on the CVSS scale. The NtfsHandler.cpp NTFS handler in 7-Zip before 24.01 (for 7zz) contains a heap-based buffer overflow that allows an attacker to overwrite two bytes at multiple offsets beyond the allocated buffer size: buffer+512*i-2, for i=9, i=10, i=11, etc.. EPSS estimates a 0.34% chance of exploitation in the next 30 days.
