CVE Vulnerabilities for 7Zip
| CVE | Published | Severity | Details | Exploitability | Impact | Vector |
|---|---|---|---|---|---|---|
| CVE‑2024‑11477 | 2024‑11‑22 21:15:09 | HIGH (8) | 7-Zip Zstandard Decompression Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the implementation of Zstandard decompression. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24346. | 2 | 6 | LOCAL |
| CVE‑2023‑31102 | 2023‑11‑03 04:15:21 | HIGH (8) | Ppmd7.c in 7-Zip before 23.00 allows an integer underflow and invalid read operation via a crafted 7Z archive. | 2 | 6 | LOCAL |
| CVE‑2022‑29072 | 2022‑04‑15 20:15:12 | HIGH (8) | 7-Zip through 21.07 on Windows allows privilege escalation and command execution when a file with the .7z extension is dragged to the Help>Contents area. This is caused by misconfiguration of 7z.dll and a heap overflow. The command runs in a child process under the 7zFM.exe process. NOTE: multiple third parties have reported that no privilege escalation can occur | 2 | 6 | LOCAL |
| CVE‑2018‑5996 | 2018‑01‑31 18:29:00 | MEDIUM (7) | 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. | 0 | 0 | NETWORK |
| CVE‑2018‑10172 | 2018‑04‑16 22:29:00 | HIGH (7) | 7-Zip through 18.01 on Windows implements the "Large memory pages" option by calling the LsaAddAccountRights function to add the SeLockMemoryPrivilege privilege to the user's account, which makes it easier for attackers to bypass intended access restrictions by using this privilege in the context of a sandboxed process. Note: This has been disputed by 3rd parties who argue this is a valid feature of Windows. | 0 | 0 | LOCAL |
| CVE‑2018‑10115 | 2018‑05‑02 21:29:00 | MEDIUM (7) | Incorrect initialization logic of RAR decoder objects in 7-Zip 18.03 and before can lead to usage of uninitialized memory, allowing remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive. | 0 | 0 | NETWORK |
| CVE‑2017‑17969 | 2018‑01‑30 16:29:00 | MEDIUM (7) | Heap-based buffer overflow in the NCompress::NShrink::CDecoder::CodeReal method in 7-Zip before 18.00 and p7zip allows remote attackers to cause a denial of service (out-of-bounds write) or potentially execute arbitrary code via a crafted ZIP archive. | 0 | 0 | NETWORK |
