| CVE-2022-0529 | A flaw was found in Unzip. The vulnerability occurs during the conversion of a wide string to a local string that leads to a heap of out-of-bound write. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution. | [email protected] | 5.5 | 0.24% | 2022-02-09 | 2024-11-21 |
| CVE-2014-8141 | Heap-based buffer overflow in the getZip64Data function in Info-ZIP UnZip 6.0 and earlier allows remote attackers to execute arbitrary code via a crafted zip file in the -t command argument to the unzip command. | [email protected] | 7.8 | 9.81% | 2020-01-31 | 2024-11-21 |
| CVE-2014-8140 | Heap-based buffer overflow in the test_compr_eb function in Info-ZIP UnZip 6.0 and earlier allows remote attackers to execute arbitrary code via a crafted zip file in the -t command argument to the unzip command. | [email protected] | 7.8 | 9.81% | 2020-01-31 | 2024-11-21 |
| CVE-2014-8139 | Heap-based buffer overflow in the CRC32 verification in Info-ZIP UnZip 6.0 and earlier allows remote attackers to execute arbitrary code via a crafted zip file in the -t command argument to the unzip command. | [email protected] | 7.8 | 9.81% | 2020-01-31 | 2024-11-21 |
| CVE-2019-13232 | Info-ZIP UnZip 6.0 mishandles the overlapping of files inside a ZIP container, leading to denial of service (resource consumption), aka a "better zip bomb" issue. | [email protected] | 3.3 | 0.05% | 2019-07-04 | 2024-11-21 |
| CVE-2018-18384 | Info-ZIP UnZip 6.0 has a buffer overflow in list.c, when a ZIP archive has a crafted relationship between the compressed-size value and the uncompressed-size value, because a buffer size is 10 and is supposed to be 12. | [email protected] | 5.5 | 3.22% | 2018-10-16 | 2024-11-21 |
| CVE-2018-1000035 | A heap-based buffer overflow exists in Info-Zip UnZip version <= 6.00 in the processing of password-protected archives that allows an attacker to perform a denial of service or to possibly achieve code execution. | [email protected] | 7.8 | 63.56% | 2018-02-09 | 2024-11-21 |
| CVE-2016-9844 | Buffer overflow in the zi_short function in zipinfo.c in Info-Zip UnZip 6.0 allows remote attackers to cause a denial of service (crash) via a large compression method value in the central directory file header. | [email protected] | 4.0 | 9.79% | 2017-01-18 | 2026-05-13 |
