The issue results from a

CVE-2023-52168 [HIGH] CVE-2023-52168: The NtfsHandler 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.

CVE-2023-52169 [HIGH] CVE-2023-52169: The NtfsHandler The NtfsHandler.cpp NTFS handler in 7-Zip before 24.01 (for 7zz) contains an out-of-bounds read that allows an attacker to read beyond the intended buffer. The bytes read beyond the intended buffer are presented as a part of a filename listed in the file system image. This has security relevance in some known web-service use cases where untrusted users can upload files and have them extracted by a server-side 7-Zip process.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SQFS file

CVE-2023-31102 [HIGH] CVE-2023-31102: Ppmd7 Ppmd7.c in 7-Zip before 23.00 allows an integer underflow and invalid read operation via a crafted 7Z archive.

CVE-2022-47069 [HIGH] CWE-787 CVE-2022-47069: p7zip 16.02 was discovered to contain a heap-buffer-overflow vulnerability via the function NArchive p7zip 16.02 was discovered to contain a heap-buffer-overflow vulnerability via the function NArchive::NZip::CInArchive::FindCd(bool) at CPP/7zip/Archive/Zip/ZipIn.cpp. NOTE: the Supplier has found that this is not a buffer overflow; at most an out-of-bounds read can occur.

CVE-2018-5996 [HIGH] CWE-119 CVE-2018-5996: Insufficient exception handling in the method NCompress::NRar3::CDecoder::Code of 7-Zip before 18.00 Insufficient exception handling in the method NCompress::NRar3::CDecoder::Code of 7-Zip before 18.00 and p7zip can lead to multiple memory corruptions within the PPMd code, allows remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.
