Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 / 11.10 : php5 vulnerabilities (USN-1231-1)

high Nessus Plugin ID 56554
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Mateusz Kocielski, Marek Kroemeke and Filip Palian discovered that a stack-based buffer overflow existed in the socket_connect function's handling of long pathnames for AF_UNIX sockets. A remote attacker might be able to exploit this to execute arbitrary code; however, the default compiler options for affected releases should reduce the vulnerability to a denial of service. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-1938)

Krzysztof Kotowicz discovered that the PHP post handler function does not properly restrict filenames in multipart/form-data POST requests.
This may allow remote attackers to conduct absolute path traversal attacks and possibly create or overwrite arbitrary files. This issue affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-2202)

It was discovered that the crypt function for blowfish does not properly handle 8-bit characters. This could make it easier for an attacker to discover a cleartext password containing an 8-bit character that has a matching blowfish crypt value. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04.
(CVE-2011-2483)

It was discovered that PHP did not properly check the return values of the malloc(3), calloc(3) and realloc(3) library functions in multiple locations. This could allow an attacker to cause a denial of service via a NULL pointer dereference or possibly execute arbitrary code.
This issue affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-3182)

Maksymilian Arciemowicz discovered that PHP did not properly implement the error_log function. This could allow an attacker to cause a denial of service via an application crash. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10, Ubuntu 11.04 and Ubuntu 11.10. (CVE-2011-3267)

Maksymilian Arciemowicz discovered that the ZipArchive functions addGlob() and addPattern() did not properly check their flag arguments. This could allow a malicious script author to cause a denial of service via application crash. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10, Ubuntu 11.04 and Ubuntu 11.10.
(CVE-2011-1657)

It was discovered that the Xend opcode parser in PHP could be interrupted while handling the shift-left, shift-right, and bitwise-xor opcodes. This could allow a malicious script author to expose memory contents. This issue affected Ubuntu 10.04 LTS.
(CVE-2010-1914)

It was discovered that the strrchr function in PHP could be interrupted by a malicious script, allowing the exposure of memory contents. This issue affected Ubuntu 8.04 LTS. (CVE-2010-2484).

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
