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

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

We recommend that you upgrade your php-guzzlehttp-psr7 packages.
