Description

A buffer overflow was found in the way unzip uncompressed certain extra fields of a file. A specially crafted Zip archive could cause unzip to crash or, possibly, execute arbitrary code when the archive was tested with unzip's '-t' option. (CVE-2014-9636)

A buffer overflow flaw was found in the way unzip computed the CRC32 checksum of certain extra fields of a file. A specially crafted Zip archive could cause unzip to crash when the archive was tested with unzip's '-t' option. (CVE-2014-8139)

An integer underflow flaw, leading to a buffer overflow, was found in the way unzip uncompressed certain extra fields of a file. A specially crafted Zip archive could cause unzip to crash when the archive was tested with unzip's '-t' option. (CVE-2014-8140)

A buffer overflow flaw was found in the way unzip handled Zip64 files. A specially crafted Zip archive could possibly cause unzip to crash when the archive was uncompressed. (CVE-2014-8141)
