Description

This security bulletin contains information about 4 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2007-4782)

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 (application crash) via (1) a long string in the pattern parameter to the glob function; or (2) a long string in the string parameter to the fnmatch function, accompanied by a pattern parameter value with undefined characteristics, as demonstrated by a "*[1]e" value.


2) Input validation error (CVE-ID: CVE-2007-2872)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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/E:P/U:Green


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Multiple integer overflows in the chunk_split function in PHP 5 before 5.2.3 and PHP 4 before 4.4.8 allow remote attackers to cause a denial of service (crash) or execute arbitrary code via the (1) chunks, (2) srclen, and (3) chunklen arguments.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2007-3007)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: 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/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

PHP 5 before 5.2.3 does not enforce the open_basedir or safe_mode restriction in certain cases, which allows context-dependent attackers to determine the existence of arbitrary files by checking if the readfile function returns a string. NOTE: this issue might also involve the realpath function.


4) Buffer overflow (CVE-ID: CVE-2007-1887)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: 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/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Buffer overflow in the sqlite_decode_binary function in the bundled sqlite library in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 allows context-dependent attackers to execute arbitrary code via an empty value of the in parameter, as demonstrated by calling the sqlite_udf_decode_binary function with a 0x01 character.
