Due to improper path sanitization, archives containing relative file paths can cause files to be written (or overwritten) outside of the target directory.

CriticalCVSS 9.1 EPSS 1.4%
-
LowCVSS 3.3 EPSS 0.62%
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.
-
MediumCVSS 5.5 EPSS 2.4%
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.

MediumCVSS 5.5 EPSS 2.1%
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.
-
HighCVSS 7.8 EPSS 7.4%
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.
-
HighCVSS 7.8 EPSS 7.4%
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.
-
HighCVSS 7.8 EPSS 7.4%
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.
-
LowCVSS 3.3 EPSS 0.50%
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.
-
MediumCVSS 5.5 EPSS 2.6%
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.
-
HighCVSS 7.8 EPSS 30.1%
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.
-
MediumCVSS 4.0 EPSS 1.8%
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.
-
MediumCVSS 4.0 EPSS 1.5%
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.
-
MediumCVSS 4.3 EPSS 6.1%
Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (infinite loop) via empty bzip2 data in a ZIP archive.
-
MediumCVSS 6.8 EPSS 7.2%
Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive, possibly related to an Extra-Field size value.
-
MediumCVSS 5.0 EPSS 11.9%
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.
-
HighCVSS 9.3 EPSS 6.3%
The NEEDBITS macro in the inflate_dynamic function in inflate.c for unzip can be invoked using invalid buffers, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors that trigger a free of uninitialized or previ...
