Medium
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L |
Name of the Vulnerable Software and Affected Versions
PHP versions 7.2.x below 7.2.9
PHP versions 7.3.x below 7.3.16
PHP versions 7.4.x below 7.4.4
Description
The issue is related to the
exif read data() function in PHP, which can cause the language to read one byte of uninitialized memory while parsing EXIF data. This could potentially lead to information disclosure or crash. The vulnerability is associated with reading data beyond the buffer boundaries in memory, allowing a remote attacker to gain unauthorized access to protected information or cause a denial of service.Recommendations
For PHP versions 7.2.x below 7.2.9, update to version 7.2.9 or later to resolve the issue.
For PHP versions 7.3.x below 7.3.16, update to version 7.3.16 or later to resolve the issue.
For PHP versions 7.4.x below 7.4.4, update to version 7.4.4 or later to resolve the issue.
As a temporary workaround, consider restricting the use of the
exif read data() function until a patch is available.Exploit
