CVE-2008-2829: Canonical Ubuntu Linux

Medium severity, CVSS 5.0. EPSS: 5.3% chance of exploitation in the next 30 days.

php_imap.c in PHP 5.2.5, 5.2.6, 4.x, and other versions, uses obsolete API calls that allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long IMAP request, which triggers an "rfc822.c legacy routine buffer overflow" error message, related to the rfc822_write_address function.

Affected products

• Canonical Ubuntu Linux: version 6.06 only; version 7.04 only; version 7.10 only; version 8.04 only
• PHP PHP: up to and including 4.4.9; version 5.2.5 only; version 5.2.6 only
