security flaw

Directory traversal vulnerability in Info-ZIP UnZip 5.42 and earlier allows attackers to overwrite arbitrary files during archive extraction via a .. (dot dot) in an extracted filename.

security flaw

Info-ZIP UnZip 5.42 and earlier allows attackers to overwrite arbitrary files during archive extraction via filenames in the archive that begin with the '/' (slash) character.

security flaw

Directory traversal vulnerability in UnZip 5.50 allows attackers to overwrite arbitrary files via invalid characters between two . (dot) characters, which are filtered and result in a ".." sequence.

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.

security flaw

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.

security flaw

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.

unzip: charset_to_intern() buffer overflow

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: Invalid access in the LZMA compression algorithm

An out-of-bounds read exists in Info-Zip UnZip version 6.10c22 that allows an attacker to perform a denial of service and read sensitive memory.

unzip: Heap-based out-of-bounds access in extract.c:ef_scan_for_stream() possibly causing crash

An out-of-bounds read exists in Info-Zip UnZip version 6.10c22 that allows an attacker to perform a denial of service and read sensitive memory.

unzip: Heap-based buffer overflow in charset_to_intern()

A heap-based buffer overflow exists in Info-Zip UnZip version 6.10c22 that allows an attacker to perform a denial of service or to possibly achieve code execution.

unzip: Heap-based out-of-bounds write in fileio.c:set_zipfn_sgmnt_name() possibly causing crash

A heap-based buffer overflow exists in Info-Zip UnZip version 6.10c22 that allows an attacker to perform a denial of service or to possibly achieve code execution.
