    CVE ID         : CVE-2024-8929 CVE-2024-8932 CVE-2024-11233 CVE-2024-11234
                     CVE-2024-11236
    Debian Bug     : 1088688

    Multiple security issues were found in PHP, a widely-used open source
    general purpose scripting language, which could result in denial of
    service, authorization bypass, or information disclosure.

    CVE-2024-8929

        Sbastien Rolland discovered a partial content leak of the heap
        through heap buffer over-read in mysqlnd.

        By connecting to a fake MySQL server or tampering with network
        packets and initiating a SQL Query, it is possible to abuse
        php_mysqlnd_rset_field_rea() when parsing MySQL fields packets in
        order to include the rest of the heap content starting from the
        address of the cursor of the currently read buffer.

    CVE-2024-8932

        Yiheng Cao discovered that uncontrolled long string inputs to
        ldap_escape() on 32-bit systems can cause an integer overflow,
        resulting in an out-of-bounds write.

    CVE-2024-11233

        A memory-related vulnerability was discovered in the filter handling
        system, particularly when processing input with
        convert.quoted-printable-decode filters, which could lead to a
        segmentation fault.

        This vulnerability is triggered through specific sequences of input
        data, causing PHP to crash.  When exploited, it allows an attacker
        to extract a single byte of data from the heap or result in denial
        of service.

    CVE-2024-11234

        Lorenzo Leonardini discovered that Configuring a proxy in a stream
        context might allow for CRLF injection in URIs, which could lead to
        authorization bypass by Server Side Request Forgery attack (SSRF).

    CVE-2024-11236

        An integer overflow vulnerability was found in the firebird and
        dblib quoters, which can result in out-of-bounds writes.

    GHSA-4w77-75f9-2c8w

        A heap-use-after-free vulnerability was discovered in the
        sapi_read_post_data() function, which could allow an attacker to
        exploit memory safety issues during POST request processing.

    For Debian 11 bullseye, these problems have been fixed in version
    7.4.33-1+deb11u7.

    We recommend that you upgrade your php7.4 packages.
