Description

This security bulletin contains information about 3 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2006-5706)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary code.

Unspecified vulnerabilities in PHP, probably before 5.2.0, allow local users to bypass open_basedir restrictions and perform unspecified actions via unspecified vectors involving the (1) chdir and (2) tempnam functions. NOTE: the tempnam vector might overlap CVE-2006-1494.


2) Input validation error (CVE-ID: CVE-2006-5465)

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:U/U:Green


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

Buffer overflow in PHP before 5.2.0 allows remote attackers to execute arbitrary code via crafted UTF-8 inputs to the (1) htmlentities or (2) htmlspecialchars functions.


3) Input validation error (CVE-ID: CVE-2006-4486)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote non-authenticated attacker to corrupt data.

Integer overflow in memory allocation routines in PHP before 5.1.6, when running on a 64-bit system, allows context-dependent attackers to bypass the memory_limit restriction.
