Summary

The mail function in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 truncates e-mail messages at the first ASCIIZ ('\0') byte, which might allow context-dependent attackers to prevent intended information from being delivered in e-mail messages. NOTE: this issue might be security-relevant in cases when the trailing contents of e-mail messages are important, such as logging information or if the message is expected to be well-formed.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
