Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

It was discovered that gzip incorrectly handled certain malformed

crash or possibly execute arbitrary code with the privileges of the
user invoking the program. (CVE-2009-2624)

files compressed with the Lempel–Ziv–Welch (LZW) algorithm. If a

gzip file, an attacker could cause gzip to crash or possibly execute
arbitrary code with the privileges of the user invoking the program.
(CVE-2010-0001).
