- Status
- Candidate
- Description
- 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.

- Comments
- Christey> There is active disagreement regarding whether this satisfies the | criteria for inclusion in CVE, because the attack vectors require | function parameters that are typically controlled only by the | application developer, not an external attacker. This would mean that | the PHP application owner could exploit it | | Since various PHP functions already allow the application owner to | execute commands, no additional privileges would be gained by | exploiting such a bug. However, if safe_mode is enabled in PHP, then | the PHP functions related to execution are restricted | (e.g. shell_exec()). Thus, exploitation may allow the PHP application | owner to execute code *despite* the configured restrictions imposed by | safe mode, which then qualifies this as a vulnerability.
