CVE-2020-7063

In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when creating PHAR archive using PharData::buildFromIterator() function, the files are added with default permissions (0666, or all access) even if the original files on the filesystem were with more restrictive permissions. This may result in files having more lax permissions than intended when such archive is extracted.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

The following packages have been upgraded to a later upstream version: php (7.3.20). (BZ#1856655)

Security Fix(es):

• php: Out-of-bounds read due to integer overflow in iconv_mime_decode_headers() (CVE-2019-11039)

• php: Buffer over-read in exif_read_data() (CVE-2019-11040)

• php: Using mb_strtolower() function with UTF-32LE encoding leads to potential code execution (CVE-2020-7065)

• php: Heap buffer over-read in exif_scan_thumbnail() (CVE-2019-11041)

• php: Heap buffer over-read in exif_process_user_comment() (CVE-2019-11042)
