An integer overflow vulnerability leading to a heap overflow in the file ..\php-5.3.6\ext\phar\tar.c.
|
|
|
|
|
|
int phar_parse_tarfile(php_stream* fp, char *fname, int fname_len, char *alias, int alias_len, phar_archive_data** pphar, int is_data, php_uint32 compression, char **error TSRMLS_DC) /* {{{ */
|
|
{
|
|
//.....
|
|
size = entry.uncompressed_filesize = entry.compressed_filesize =
|
|
phar_tar_number(hdr->size, sizeof(hdr->size)); //(*)
|
|
//.....
|
|
if (!last_was_longlink && hdr->typeflag == 'L') {
|
|
last_was_longlink = 1;
|
|
/* support the ././@LongLink system for storing long filenames */
|
|
entry.filename_len = entry.uncompressed_filesize;
|
|
entry.filename = pemalloc(entry.filename_len+1, myphar->is_persistent); //(**)
|
|
|
|
read = php_stream_read(fp, entry.filename, entry.filename_len); //(***)
|
|
//.....
|
|
|
|
If entry.filename_len(which attacker can control) equal 0xffffffff, pemalloc() will allocate zero length buffer. Then php_stream_read() get as a length parameter 0xffffffff value. Because php_stream_read () checks that the passed length does not exceed the amount of data available, the buffer overflow sizes are available from the data stream.
