The (1) ZipArchive::addGlob and (2) ZipArchive::addPattern functions in ext/zip/php_zip.c in PHP 5.3.6 allow context-dependent attackers to cause a denial of service (application crash) via certain flags arguments, as demonstrated by (a) GLOB_ALTDIRFUNC and (b) GLOB_APPEND.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - php: buffer overflow in handling of long link names in tar phar archives (CVE-2016-2554)

  - php: Uninitialized read in exif_process_IFD_in_TIFF (CVE-2019-9641)

  - The ip2long function in PHP 5.1.4 and earlier may incorrectly validate an arbitrary string and return a     valid network IP address, which allows remote attackers to obtain network information and facilitate other     attacks, as demonstrated using SQL injection in the X-FORWARDED-FOR Header in index.php in MiniBB 2.0.
    NOTE: it could be argued that the ip2long behavior represents a risk for security-relevant issues in a way     that is similar to strcpy's role in buffer overflows, in which case this would be a class of     implementation bugs that would require separate CVE items for each PHP application that uses ip2long in a     security-relevant manner. (CVE-2006-4023)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Multiple vulnerabilities has been identified and fixed in php :

Use-after-free vulnerability in the substr_replace function in PHP 5.3.6 and earlier allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact by using the same variable for multiple arguments (CVE-2011-1148).

The (1) ZipArchive::addGlob and (2) ZipArchive::addPattern functions in ext/zip/php_zip.c in PHP 5.3.6 allow context-dependent attackers to cause a denial of service (application crash) via certain flags arguments, as demonstrated by (a) GLOB_ALTDIRFUNC and (b) GLOB_APPEND (CVE-2011-1657).

Stack-based buffer overflow in the socket_connect function in ext/sockets/sockets.c in PHP 5.3.3 through 5.3.6 might allow context-dependent attackers to execute arbitrary code via a long pathname for a UNIX socket (CVE-2011-1938).

The rfc1867_post_handler function in main/rfc1867.c in PHP before 5.3.7 does not properly restrict filenames in multipart/form-data POST requests, which allows remote attackers to conduct absolute path traversal attacks, and possibly create or overwrite arbitrary files, via a crafted upload request, related to a file path injection vulnerability. (CVE-2011-2202).

crypt_blowfish before 1.1, as used in PHP before 5.3.7 on certain platforms, does not properly handle 8-bit characters, which makes it easier for context-dependent attackers to determine a cleartext password by leveraging knowledge of a password hash (CVE-2011-2483).

PHP before 5.3.7 does not properly check the return values of the malloc, calloc, and realloc library functions, which allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) or trigger a buffer overflow by leveraging the ability to provide an arbitrary value for a function argument, related to (1) ext/curl/interface.c, (2) ext/date/lib/parse_date.c, (3) ext/date/lib/parse_iso_intervals.c, (4) ext/date/lib/parse_tz.c, (5) ext/date/lib/timelib.c, (6) ext/pdo_odbc/pdo_odbc.c, (7) ext/reflection/php_reflection.c, (8) ext/soap/php_sdl.c, (9) ext/xmlrpc/libxmlrpc/base64.c, (10) TSRM/tsrm_win32.c, and (11) the strtotime function (CVE-2011-3182).

PHP before 5.3.7 does not properly implement the error_log function, which allows context-dependent attackers to cause a denial of service (application crash) via unspecified vectors (CVE-2011-3267).

Buffer overflow in the crypt function in PHP before 5.3.7 allows context-dependent attackers to have an unspecified impact via a long salt argument, a different vulnerability than CVE-2011-2483 (CVE-2011-3268).

The updated php packages have been upgraded to 5.3.8 which is not vulnerable to these issues.

Additionally some of the PECL extensions has been upgraded and/or rebuilt for the new php version.

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.

The remote host is affected by the vulnerability described in GLSA-201110-06 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       CVE identifiers referenced below for details.
  Impact :

    A context-dependent attacker could execute arbitrary code, obtain       sensitive information from process memory, bypass intended access       restrictions, or cause a Denial of Service in various ways.
    A remote attacker could cause a Denial of Service in various ways,       bypass spam detections, or bypass open_basedir restrictions.
  Workaround :

    There is no known workaround at this time.
