| CVE | Weakness | CVSS v3 | Details |
|---|---|---|---|
| CVE-2017-8923 | CWE-787 Out-of-bounds Write | 9.8 Critical |
CVE-2017-8923 The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script's use of .= with a long string. Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3. Contact customer support to receive patch and update information Affected, fixed & timelineAffected:
|
| CVE-2017-9120 | CWE-190 Integer Overflow or Wraparound | 9.8 Critical |
CVE-2017-9120 PHP 7.x through 7.1.5 allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a long string because of an Integer overflow in mysqli_real_escape_string. Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3. Contact customer support to receive patch and update information Affected, fixed & timelineAffected:
|
| CVE-2021-43527 | CWE-787 Out-of-bounds Write | 9.8 Critical |
CVE-2021-43527 NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS #7, or PKCS #12 are likely to be impacted. Applications using NSS for certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how they configure NSS. Note: This vulnerability does NOT impact Mozilla Firefox. However, email clients and PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1. Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3. Contact customer support to receive patch and update information Affected, fixed & timelineAffected:
|
| CVE-2022-3515 | CWE-190 Integer Overflow or Wraparound | 9.8 Critical |
CVE-2022-3515 A vulnerability was found in the Libksba library due to an integer overflow within the CRL parser. The vulnerability can be exploited remotely for code execution on the target system by passing specially crafted data to the application, for example, a malicious S/MIME attachment. Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3. Contact customer support to receive patch and update information Affected, fixed & timelineAffected:

|
| CVE-2022-1271 | CWE-20 Improper Input Validation | 8.8 High |
CVE-2022-1271 An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system. Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3. Contact customer support to receive patch and update information Affected, fixed & timelineAffected:
|
| CVE-2021-21708 | CWE-416 Use After Free | 8.2 High |

An attacker can use this flaw via the RSA decryption API to decrypt parts of the cipher text encrypted with RSA. Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3. Contact customer support to receive patch and update information Affected, fixed & timelineAffected:
|
| CVE-2023-38802 | CWE-754 Improper Check for Unusual or Exceptional Conditions | 7.5 High |
CVE-2023-38802 FRRouting FRR 7.5.1 through 9.0 and Pica8 PICOS 4.3.3.2 allow a remote attacker to cause a denial of service via a crafted BGP update with a corrupted attribute 23 (Tunnel Encapsulation). Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3. Contact customer support to receive patch and update information Affected, fixed & timelineAffected:
|
| CVE-2024-2551 | CWE-476 NULL Pointer Dereference | 7.5 High |
CVE-2024-2551 A null pointer dereference vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to stop a core system service on the firewall by sending a crafted packet through the data plane that causes a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the firewall entering maintenance mode. Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3. Contact customer support to receive patch and update information Affected, fixed & timelineAffected:
|
| CVE-2023-0286 | CWE-843 Access of Resource Using Incompatible Type ('Type Confusion') | 7.4 High |
CVE-2023-0286 There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network. Mitigation: Disable CRL (certification revocation list) checking, if possible Vendor fix: Upgrade Palo Alto Networks Virtual NGFW V11.1.2-h3.
