Vulnerability from csaf_redhat - Published: 2005-01-19 18:46 - Updated: 2024-11-14 10:03
Summary
Red Hat Security Advisory: php security update
Severity
Important
Notes
Topic: Updated php packages that fix various security issues are now available for Red Hat Enterprise Linux 2.1.
Details: PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server. A double-free bug was found in the deserialization code of PHP. PHP applications use the unserialize function on untrusted user data, which could allow a remote attacker to gain access to memory or potentially execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1019 to this issue. Flaws were found in the pack and unpack PHP functions. These functions do not normally pass user supplied data, so they would require a malicious PHP script to be exploited. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1018 to this issue. A bug was discovered in the initialization of the OpenSSL library, such that the curl extension could not be used to perform HTTP requests over SSL unless the php-imap package was installed. Users of PHP should upgrade to these updated packages, which contain fixes for these issues.

CVE-2004-1018

Multiple integer handling errors in PHP before 4.3.10 allow attackers to bypass safe mode restrictions, cause a denial of service, or execute arbitrary code via (1) a negative offset value to the shmop_write function, (2) an "integer overflow/underflow" in the pack function, or (3) an "integer overflow/underflow" in the unpack function. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

Vendor Fix Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ https://access.redhat.com/errata/RHSA-2005:031
CVE-2004-1019

The deserialization code in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to cause a denial of service and execute arbitrary code via untrusted data to the unserialize function that may trigger "information disclosure, double-free and negative reference index array underflow" results.
