Package : php-guzzlehttp-psr7 Version : 1.4.2-0.1+deb10u2 CVE ID : CVE-2023-29197 Debian Bug : 1034581 It was discovered that php-guzzlehttp-psr7, a PSR-7 message implementation, performed improper header parsing, which may lead to information disclosure or authorization bypass. An attacker could sneak in a newline (\n) into both the header names and values. While the specification states that \r\n\r\n is used to terminate the header list, many servers in the wild will also accept \n\n. This is a follow-up to CVE-2022-24775 where the fix was incomplete. For Debian 10 buster, these problems have been fixed in version 1.4.2-0.1+deb10u2. We recommend that you upgrade your php-guzzlehttp-psr7 packages. For the detailed security status of php-guzzlehttp-psr7 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/php-guzzlehttp-psr7 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS
