A vulnerability, which was classified as problematic, has been found in PHP up to 4.3.10/5.0.3 (Programming Language Software). Affected by this issue is the function magic_quotes_gpc of the component Upload Handler. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, and integrity. CVE summarizes:

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.
