CVE-2007-4657

Status Candidate

Overview

Multiple integer overflows in PHP 4 before 4.4.8, and PHP 5 before 5.2.4, allow remote attackers to obtain sensitive information (memory contents) or cause a denial of service (thread crash) via a large len value to the (1) strspn or (2) strcspn function, which triggers an out-of-bounds read. NOTE: this affects different product versions than CVE-2007-3996.

Debian Linux Security Advisory 1578-1
Posted May 20, 2008
Authored by Debian | Site debian.org

Debian Security Advisory 1578-1 - Several vulnerabilities have been discovered in PHP version 4, a server-side, HTML-embedded scripting language. The session_start function allows remote attackers to insert arbitrary attributes into the session cookie via special characters in a cookie that is obtained from various parameters. A denial of service was possible through a malicious script abusing the glob() function. Certain maliciously constructed input to the wordwrap() function could lead to a denial of service attack. Large len values of the stspn() or strcspn() functions could allow an attacker to trigger integer overflows to expose memory or cause denial of service. The escapeshellcmd API function could be attacked via incomplete multibyte chars.

Gentoo Linux Security Advisory 200710-2
Posted Oct 9, 2007
Authored by Gentoo | Site security.gentoo.org

Gentoo Linux Security Advisory GLSA 200710-02 - Several vulnerabilities were found in PHP. Mattias Bengtsson and Philip Olausson reported integer overflows in the gdImageCreate() and gdImageCreateTrueColor() functions of the GD library which can cause heap-based buffer overflows. Gerhard Wagner discovered an integer overflow in the chunk_split() function that can lead to a heap-based buffer overflow. Its incomplete fix caused incorrect buffer size calculation due to precision loss, also resulting in a possible heap-based buffer overflow. A buffer overflow in the sqlite_decode_binary() of the SQLite extension found by Stefan Esser that was addressed in PHP 5.2.1 was not fixed correctly. Versions less than 5.2.4_p20070914-r2 are affected.
