Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (infinite loop) via empty bzip2 data in a ZIP archive.

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.

Buffer overflow in the charset_to_intern function in unix/unix.c in Info-Zip UnZip 6.10b allows remote attackers to execute arbitrary code via a crafted string, as demonstrated by converting a string from CP866 to UTF-8.

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.

Directory traversal vulnerability in the R-Company Unzipper application 1.0.1 and earlier for Android allows remote attackers to overwrite or create arbitrary files via a crafted filename.

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 previously-freed data.

Buffer overflow in (1) TZipBuilder 1.79.03.01, (2) Abakt 0.9.2 and 0.9.3-beta1, (3) CAM UnZip 4.0 and 4.3, and possibly other products, allows user-assisted attackers to execute arbitrary code via a ZIP archive that contains a file with a long file name.

Buffer overflow in UnZip 5.50 and earlier allows user-assisted attackers to execute arbitrary code via a long filename command line argument. NOTE: since the overflow occurs in a non-setuid program, there are not many scenarios under which it poses a vulnerability, unless unzip is passed long arguments when it is invoked from other programs.

Race condition in Unzip 5.52 allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by Unzip after the decompression is complete.

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.
