Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Auke van Slooten discovered that PHP incorrectly handled certain
xmlrpc requests. An attacker could exploit this issue to cause the PHP
server to crash, resulting in a denial of service. This issue only
affected Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and 9.10. (CVE-2010-0397)

It was discovered that the pseudorandom number generator in PHP did
not provide the expected entropy. An attacker could exploit this issue
to predict values that were intended to be random, such as session
cookies. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and
9.10. (CVE-2010-1128)

It was discovered that PHP did not properly handle directory pathnames
that lacked a trailing slash character. An attacker could exploit this
issue to bypass safe_mode restrictions. This issue only affected
Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and 9.10. (CVE-2010-1129)

Grzegorz Stachowiak discovered that the PHP session extension did not
properly handle semicolon characters. An attacker could exploit this
issue to bypass safe_mode restrictions. This issue only affected
Ubuntu 8.04 LTS, 9.04 and 9.10. (CVE-2010-1130)

Stefan Esser discovered that PHP incorrectly decoded remote HTTP
chunked encoding streams. An attacker could exploit this issue to
cause the PHP server to crash and possibly execute arbitrary code with
application privileges. This issue only affected Ubuntu 10.04 LTS.
(CVE-2010-1866)

Mateusz Kocielski discovered that certain PHP SQLite functions
incorrectly handled empty SQL queries. An attacker could exploit this
issue to possibly execute arbitrary code with application privileges.
(CVE-2010-1868)

Mateusz Kocielski discovered that PHP incorrectly handled certain
arguments to the fnmatch function. An attacker could exploit this flaw
and cause the PHP server to consume all available stack memory,
resulting in a denial of service. (CVE-2010-1917)

Stefan Esser discovered that PHP incorrectly handled certain strings
in the phar extension. An attacker could exploit this flaw to possibly
view sensitive information. This issue only affected Ubuntu 10.04 LTS.
(CVE-2010-2094, CVE-2010-2950)

Stefan Esser discovered that PHP incorrectly handled deserialization
of SPLObjectStorage objects. A remote attacker could exploit this
issue to view sensitive information and possibly execute arbitrary
code with application privileges. This issue only affected Ubuntu 8.04
LTS, 9.04, 9.10 and 10.04 LTS. (CVE-2010-2225)

It was discovered that PHP incorrectly filtered error messages when
limits for memory, execution time, or recursion were exceeded. A
remote attacker could exploit this issue to possibly view sensitive
information. (CVE-2010-2531)

Stefan Esser discovered that the PHP session serializer incorrectly
handled the PS_UNDEF_MARKER marker. An attacker could exploit this
issue to alter arbitrary session variables. (CVE-2010-3065).
