Title: Microsoft’s security update includes 84 vulnerabilities, one that’s exploited in the wild

Description: Microsoft released its monthly security update Tuesday, disclosing more than 80 vulnerabilities in the company’s various software, hardware and firmware offerings, including one that’s actively being exploited in the wild. July's security update features three critical vulnerabilities, up from one last month, still lower than Microsoft’s average in a Patch Tuesday. All the other vulnerabilities fixed are considered “important.” All three critical vulnerabilities allow remote code execution on Microsoft Windows Systems. Of these, Microsoft considers the exploitation of CVE-2022-22029, CVE-2022-22038 and CVE-2022-22039 less likely to occur. CVE-2022-22029 could be exploited over the network by making an unauthenticated, specially crafted call to a Network File System (NFS). However, according to Microsoft, it has high attack complexity and would require repeated exploitation attempts through sending constant or intermittent data. Another critical vulnerability, CVE-2022-22038, is also considered to be more difficult to exploit because it requires undisclosed additional actions by an attacker to prepare the target environment for exploitation. CVE-2022-22039 iss another remote code execution flaw in Windows Network File System that requires an attacker to win a race condition to exploit it, making this vulnerability less likely to be exploited.


Snort SIDs: 60191, 60192, 60198, 60199, 60201, 60202, 60206, 60207, 60213 and 60214. Additionally, Snort 3 SIDs: 300215 and 300216.

Title: Adobe discloses critical vulnerabilities in Acrobat, Reader and Photoshop

Description: Adobe released a large swath of patches for its products Tuesday, including disclosing 22 vulnerabilities in Adobe Acrobat Reader, some of which could lead to arbitrary code execution. Affected product versions include Acrobat DC, Acrobat Reader DC, Acrobat 2020, Acrobat 2017 and Acrobat Reader 2017. Cisco Talos discovered one of the vulnerabilities, CVE-2022-34230, a use-after-free issue that is triggered if the targeted user opens a PDF with specially crafted, malicious JavaScript. The code could give attackers control over reused memory, which can lead to arbitrary code execution.

ID: CVE-2022-32032

Title: Stack-based overflow vulnerability in Tenda AX1806 v1.0.0.1

Description: Tenda AX1806 v1.0.0.1 was discovered to contain a stack overflow vulnerability that affects the function formAddMacfilterRule. The manipulation of the argument deviceList with an unknown input can lead to a memory corruption vulnerability.

CVSS v3.1 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

ID: CVE-2022-25900

Title: Command injection vulnerability in git-clone

Description: All versions of package git-clone are vulnerable to Command Injection due to insecure usage of the --upload-pack feature of git. The use of the --upload-pack feature of git is also supported for git clone and allows users to execute arbitrary commands on the OS.

CVSS v3.1 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

ID: CVE-2022-2274

Title: Heap memory corruption with RSA private key operation

Description: The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048-bit private keys

incorrect on such machines and memory corruption will happen during the computation. Because of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048-bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue.

CVSS v3.1 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
