Description
This security bulletin contains information about 12 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2010-0397)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: []
The vulnerability allows context-dependent attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and application crash) and possibly have unspecified other impact via a crafted argument.
2) Cryptographic issues (CVE-ID: CVE-2010-1128)
CWE-ID: CWE-310 - Cryptographic Issues
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The Linear Congruential Generator (LCG) in PHP before 5.2.13 does not provide the expected entropy, which makes it easier for context-dependent attackers to guess values that were intended to be unpredictable, as demonstrated by session cookies generated by using the uniqid function.
3) Input validation error (CVE-ID: CVE-2010-1129)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The safe_mode implementation in PHP before 5.2.13 does not properly handle directory pathnames that lack a trailing / (slash) character, which allows context-dependent attackers to bypass intended access restrictions via vectors related to use of the tempnam function.
4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2010-1130)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to corrupt data.
session.c in the session extension in PHP before 5.2.13, and 5.3.1, does not properly interpret ; (semicolon) characters in the argument to the session_save_path function, which allows context-dependent attackers to bypass open_basedir and safe_mode restrictions via an argument that contains multiple ; characters in conjunction with a .. (dot dot).
5) Integer overflow (CVE-ID: CVE-2010-1866)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The dechunk filter in PHP 5.3 through 5.3.2, when decoding an HTTP chunked encoding stream, allows context-dependent attackers to cause a denial of service (crash) and possibly trigger memory corruption via a negative chunk size, which bypasses a signed comparison, related to an integer overflow in the chunk size decoder.
6) Code Injection (CVE-ID: CVE-2010-1868)
CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The (1) sqlite_single_query and (2) sqlite_array_query functions in ext/sqlite/sqlite.c in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allow context-dependent attackers to execute arbitrary code by calling these functions with an empty SQL query, which triggers access of uninitialized memory.
7) Resource management error (CVE-ID: CVE-2010-1917)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
Stack consumption vulnerability in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allows context-dependent attackers to cause a denial of service (PHP crash) via a crafted first argument to the fnmatch function, as demonstrated using a long string.
8) Format string error (CVE-ID: CVE-2010-2094)
CWE-ID: CWE-134 - Use of Externally-Controlled Format String
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Multiple format string vulnerabilities in the phar extension in PHP 5.3 before 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, or (4) phar_wrapper_open_url functions in ext/phar/stream.c; and the (5) phar_wrapper_open_dir function in ext/phar/dirstream.c, which triggers errors in the php_stream_wrapper_log_error function.
9) Use-after-free (CVE-ID: CVE-2010-2225)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing serialized data, related to the PHP unserialize function. A remote attackers can execute arbitrary code or obtain sensitive information.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
10) Information disclosure (CVE-ID: CVE-2010-2531)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The var_export function in PHP 5.2 before 5.2.14 and 5.3 before 5.3.3 flushes the output buffer to the user when certain fatal errors occur, even if display_errors is off, which allows remote attackers to obtain sensitive information by causing the application to exceed limits for memory, execution time, or recursion.
11) Format string error (CVE-ID: CVE-2010-2950)
CWE-ID: CWE-134 - Use of Externally-Controlled Format String
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Format string vulnerability in stream.c in the phar extension in PHP 5.3.x through 5.3.3 allows context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the phar_stream_flush function, leading to errors in the php_stream_wrapper_log_error function. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-2094.
12) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2010-3065)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to corrupt data.
The default session serializer in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 does not properly handle the PS_UNDEF_MARKER marker, which allows context-dependent attackers to modify arbitrary session variables via a crafted session variable name.
