CVE-2014-9636 [MEDIUM] CWE-119 CVE-2014-9636: unzip 6.0 allows remote attackers to cause a denial of service (out-of-bounds read or write and cras unzip 6.0 allows remote attackers to cause a denial of service (out-of-bounds read or write and crash) via an extra field with an uncompressed size smaller than the compressed field size in a zip archive that advertises STORED method compression.

CVE-2022-0529 [MEDIUM] CWE-787 CVE-2022-0529: A flaw was found in Unzip. The vulnerability occurs during the conversion of a wide string to a loca 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.

CVE-2022-0530 [MEDIUM] CVE-2022-0530: A flaw was found in Unzip. The vulnerability occurs during the conversion of a wide string to a loca 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.

CVE-2015-7697 [MEDIUM] CWE-399 CVE-2015-7697: Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (infinite loop) via empty bz Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (infinite loop) via empty bzip2 data in a ZIP archive.

CVE-2018-18384 [MEDIUM] CWE-119 CVE-2018-18384: Info-ZIP UnZip 6.0 has a buffer overflow in list.c, when a ZIP archive has a crafted relationship be 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.

CVE-2005-0602 [MEDIUM] CVE-2005-0602: Unzip 5 Unzip 5.51 and earlier does not properly warn the user when extracting setuid or setgid files, which may allow local users to gain privileges.

CVE-2014-9913 [MEDIUM] CWE-119 CVE-2014-9913: Buffer overflow in the list_files function in list.c in Info-Zip UnZip 6.0 allows remote attackers t Buffer overflow in the list_files function in list.c in Info-Zip UnZip 6.0 allows remote attackers to cause a denial of service (crash) via vectors related to the compression method.

CVE-2021-4217 [LOW] CWE-476 CVE-2021-4217: A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, whi A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, which can lead to a null pointer dereference. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.
