Last modified: 2023-10-26 10:35:37 UTC
CVE-2019-9637 Multiple security issues were found in PHP, a widely-used open source general purpose scripting language: The EXIF extension had multiple cases of invalid memory access and rename() was implemented insecurely. For the stable distribution (stretch), this problem has been fixed in version 7.0.33-0+deb9u3. We recommend that you upgrade your php7.0 packages. For the detailed security status of php7.0 please refer to its security tracker page at: \ https://security-tracker.debian.org/tracker/php7.0 References: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2019-9637 http://www.debian.org/security/2019/dsa-4403
