[Buildroot] [PATCH 2/2] package/ofono: security bump to v2.18

[Titouan Christophe via buildroot]

This fixes the following vulnerabilities:

- CVE-2023-2794:
    A flaw was found in ofono, an Open Source Telephony on Linux. A stack
    overflow bug is triggered within the decode_deliver() function during
    the SMS decoding. It is assumed that the attack scenario is accessible
    from a compromised modem, a malicious base station, or just SMS. There
    is a bound check for this memcpy length in decode_submit(), but it was
    forgotten in decode_deliver().
    https://www.cve.org/CVERecord?id=CVE-2023-2794

- CVE-2024-7537:
    oFono QMI SMS Handling Out-Of-Bounds Read Information Disclosure
    Vulnerability. This vulnerability allows local attackers to disclose
    sensitive information on affected installations of oFono.
    Authentication is not required to exploit this vulnerability.  The
    specific flaw exists within the processing of SMS message lists. The
    issue results from the lack of proper validation of user-supplied
    data, which can result in a read past the end of an allocated buffer.
    An attacker can leverage this in conjunction with other
    vulnerabilities to execute arbitrary code in the context of root. Was
    ZDI-CAN-23157.
    https://www.cve.org/CVERecord?id=CVE-2024-7537

- CVE-2024-7539:
    oFono CUSD Stack-based Buffer Overflow Code Execution Vulnerability.
    This vulnerability allows local attackers to execute arbitrary code on
    affected installations of oFono. An attacker must first obtain the
    ability to execute code on the target modem in order to exploit this
    vulnerability.  The specific flaw exists within the parsing of
    responses from AT+CUSD commands. The issue results from the lack of
    proper validation of the length of user-supplied data prior to copying
    it to a stack-based buffer. An attacker can leverage this
    vulnerability to execute code in the context of root. Was ZDI-
    CAN-23195.
    https://www.cve.org/CVERecord?id=CVE-2024-7539

- CVE-2024-7540:
    oFono AT CMGL Command Uninitialized Variable Information Disclosure
    Vulnerability. This vulnerability allows local attackers to disclose
    sensitive information on affected installations of oFono. An attacker
    must first obtain the ability to execute code on the target modem in
    order to exploit this vulnerability.  The specific flaw exists within
    the parsing of responses from AT+CMGL commands. The issue results from
    the lack of proper initialization of memory prior to accessing it. An
    attacker can leverage this in conjunction with other vulnerabilities
    to execute arbitrary code in the context of root. Was ZDI-CAN-23307.
    https://www.cve.org/CVERecord?id=CVE-2024-7540

- CVE-2024-7541:
    oFono AT CMT Command Uninitialized Variable Information Disclosure
    Vulnerability. This vulnerability allows local attackers to disclose
    sensitive information on affected installations of oFono. An attacker
    must first obtain the ability to execute code on the target modem in
    order to exploit this vulnerability.  The specific flaw exists within
    the parsing of responses from AT+CMT commands. The issue results from
    the lack of proper initialization of memory prior to accessing it. An
    attacker can leverage this in conjunction with other vulnerabilities
    to execute arbitrary code in the context of root. Was ZDI-CAN-23308.
    https://www.cve.org/CVERecord?id=CVE-2024-7541

- CVE-2024-7542:
    oFono AT CMGR Command Uninitialized Variable Information Disclosure
    Vulnerability. This vulnerability allows local attackers to disclose
    sensitive information on affected installations of oFono. An attacker
    must first obtain the ability to execute code on the target modem in
    order to exploit this vulnerability.  The specific flaw exists within
    the parsing of responses from AT+CMGR commands. The issue results from
    the lack of proper initialization of memory prior to accessing it. An
    attacker can leverage this in conjunction with other vulnerabilities
    to execute arbitrary code in the context of root. Was ZDI-CAN-23309.
    https://www.cve.org/CVERecord?id=CVE-2024-7542

Also drop local patch that is no longer applicable, since upstream now
relies on HAS_BACKTRACE as well

Series applied to master, thanks.

For info, I removed the ofono package patch entry in 
.checkpackageignore,
to fix a check-package error. See:
https://gitlab.com/buildroot.org/buildroot/-/commit/611a795cfc3c39c5603be467ff98ca0839721ea6

Julien.
