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

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

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.

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.

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.

The NEEDBITS macro in the inflatedynamic 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 previously-freed data.
