Description

Tavis Ormandy from the Google Security Team discovered several vulnerabilities in gzip, the GNU compression utility. The Common Vulnerabilities and Exposures project identifies the following problems :

  • CVE-2006-4334 A NULL pointer dereference may lead to denial of service if gzip is used in an automated manner.

  • CVE-2006-4335 Missing boundary checks may lead to stack modification, allowing execution of arbitrary code.

  • CVE-2006-4336 A buffer underflow in the pack support code may lead to execution of arbitrary code.

  • CVE-2006-4337 A buffer underflow in the LZH support code may lead to execution of arbitrary code.

  • CVE-2006-4338 An infinite loop may lead to denial of service if gzip is used in an automated manner.
