CVE-2019-11047

When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what will cause it to read past the allocated buffer. This may lead to information disclosure or crash.

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: Information disclosure in exif_read_data() function (CVE-2020-7064)

• 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)
