Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : php5 vulnerabilities (USN-549-1)

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that the wordwrap function did not correctly check
lengths. Remote attackers could exploit this to cause a crash or
monopolize CPU resources, resulting in a denial of service.
(CVE-2007-3998)

Integer overflows were discovered in the strspn and strcspn functions.
Attackers could exploit this to read arbitrary areas of memory,
possibly gaining access to sensitive information. (CVE-2007-4657)

Stanislav Malyshev discovered that money_format function did not
correctly handle certain tokens. If a PHP application were tricked
into processing a bad format string, a remote attacker could execute
arbitrary code with application privileges. (CVE-2007-4658)

It was discovered that the php_openssl_make_REQ function did not
correctly check buffer lengths. A remote attacker could send a
specially crafted message and execute arbitrary code with application
privileges. (CVE-2007-4662)

It was discovered that certain characters in session cookies were not
handled correctly. A remote attacker could injection values which
could lead to altered application behavior, potentially gaining
additional privileges. (CVE-2007-3799)

Gerhard Wagner discovered that the chunk_split function did not
correctly handle long strings. A remote attacker could exploit this to
execute arbitrary code with application privileges. (CVE-2007-2872,
CVE-2007-4660, CVE-2007-4661)

Stefan Esser discovered that deeply nested arrays could be made to
fill stack space. A remote attacker could exploit this to cause a
crash or monopolize CPU resources, resulting in a denial of service.
(CVE-2007-1285, CVE-2007-4670)

Rasmus Lerdorf discovered that the htmlentities and htmlspecialchars
functions did not correctly stop when handling partial multibyte
sequences. A remote attacker could exploit this to read certain areas
of memory, possibly gaining access to sensitive information.
(CVE-2007-5898)

It was discovered that the output_add_rewrite_var fucntion would
sometimes leak session id information to forms targeting remote URLs.
Malicious remote sites could use this information to gain access to a
PHP application user's login credentials. (CVE-2007-5899).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.5
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
