------------------------------------------------------------------------- Debian LTS Advisory DLA-3986-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin December 08, 2024 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : php7.4 Version : 7.4.33-1+deb11u7 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.
