CVE-2014-8139 – unzip: CRC32 verification heap-based buffer overread (oCERT-2014-011)

https://notcve.org/view.php?id=CVE-2014-8139

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. Un desbordamiento del búfer en la región heap de la memoria en la comprobación de CRC32 en Info-ZIP UnZip versiones 6.0 y anteriores, permite a atacantes remotos ejecutar código arbitrario por medio de un archivo zip diseñado en el argumento del comando -t para el comando unzip. 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. • http://www.ocert.org/advisories/ocert-2014-011.html http://www.securitytracker.com/id/1031433 https://access.redhat.com/errata/RHSA-2015:0700 https://bugzilla.redhat.com/show_bug.cgi?id=1174844 https://access.redhat.com/security/cve/CVE-2014-8139 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
