"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."
