CVE-2023-26083 is an issue in Arm Mali GPU driver for Bifrost, Avalon, and Valhall chips, rated as having a moderate impact. The vulnerability was used to deliver spyware to Samsung devices in December 2022.

CVE-2021-29256 is a high-severity flaw that also impacts Bifrost and Midgard Arm Mali GPU kernel drivers.

The Android updates have already reached Google’s Pixel devices and some of Samsung’s Galaxy range. Given the severity of this month’s bugs, it’s a good idea to check whether the update is available and install it now.

Google Chrome 115

Google has issued the Chrome 115 update for its popular browser, fixing 20 security vulnerabilities, four of which are rated as having a high impact. CVE-2023-3727 and CVE-2023-3728 are use-after-free bugs in WebRTC. The third flaw rated as having a high severity is CVE-2023-3730, a use-after-free vulnerability in Tab Groups, while CVE-2023-3732 is an out-of-bounds memory access bug in Mojo.

Six of the flaws are listed as having a medium severity, and none of the vulnerabilities are known to have been used in real-life attacks. Even so, Chrome is a highly targeted platform, so check your system for updates.

Firefox 115

Hot on the heels of Chrome 115, rival browser Mozilla has released Firefox 115, fixing several flaws it rates as having high severity. Among these are two use-after-free bugs tracked as CVE-2023-37201 and CVE-2023-37202.

The privacy-conscious browser maker also fixed two memory safety bugs tracked as CVE-2023-37212 and CVE-2023-37211. The memory safety flaws are present in Firefox 114, Firefox ESR 102.12, and Thunderbird 102.12, Mozilla said in an advisory, adding: “Some of these bugs showed evidence of memory corruption, and we presume that with enough effort some of these could have been exploited to run arbitrary code.”

Citrix

Enterprise software giant Citrix has issued an update warning after fixing multiple flaws in its NetScaler ADC (formerly Citrix ADC) and NetScaler Gateway (formerly Citrix Gateway) tools, one of which has already been used in attacks.

Tracked as CVE-2023-3519, the already exploited flaw is an unauthenticated remote code execution vulnerability in NetScaler ADC and NetScaler Gateway that’s so severe it’s been given a CVSS score of 9.8. “Exploits of CVE-2023-3519 on unmitigated appliances have been observed,” Citrix said. “Cloud Software Group strongly urges affected customers of NetScaler ADC and NetScaler Gateway to install the relevant updated versions as soon as possible.”

The flaw was also the subject of an advisory from the US Cybersecurity and Infrastructure Security Agency (CISA), which warned that the bug was used in attacks on a critical infrastructure organization in June.

SAP

SAP, another enterprise software firm, has issued its July Security Patch Day, including 16 security fixes. The most severe flaw is CVE-2023-36922, an OS command injection vulnerability with a CVSS score of 9.1.

The bug allows an authenticated attacker to “inject an arbitrary operating system command into a vulnerable transaction and program,” security firm Onapsis said. “Patching is strongly recommended, since a successful exploit of this vulnerability has a high impact on confidentiality, integrity, and availability of the affected SAP system,” it warned.

Meanwhile, CVE-2023-33989 is a directory traversal vulnerability in SAP NetWeaver with a CVSS score of 8.7, and CVE-2023-33987 is a request smuggling and request concatenation vulnerability in SAP Web Dispatcher with a CVSS score of 8.6.

Oracle

Software company Oracle has released its July Critical Patch Update Advisory, fixing 508 vulnerabilities in its products. Among the fixes are 77 new security patches for Oracle Communications. Oracle warned that 57 of these vulnerabilities could be remotely exploited over a network without user credentials. One of the worst flaws is CVE-2023-20862, which has been given a CVSS score of 9.8.

Meanwhile, 147 of the Oracle patches were for Financial Services, and Fusion Middleware received 60 fixes.

Oracle said it continues to receive reports of attempts to exploit vulnerabilities it has already patched. In some cases, attackers were successful because targeted customers had failed to apply available Oracle patches, it said. “Oracle, therefore, strongly recommends that customers remain on actively supported versions and apply Critical Patch Update security patches without delay.”

CVE-2023-20862: CVE-2023-20862: Empty SecurityContext Is Not Properly Saved Upon Logout

In Spring Security, versions 5.7.x prior to 5.7.8, versions 5.8.x prior to 5.8.3, and versions 6.0.x prior to 6.0.3, the logout support does not properly clean the security context if using serialized versions. Additionally, it is not possible to explicitly save an empty security context to the HttpSessionSecurityContextRepository. This vulnerability can keep users authenticated even after they performed logout. Users of affected versions should apply the following mitigation. 5.7.x users should upgrade to 5.7.8. 5.8.x users should upgrade to 5.8.3. 6.0.x users should upgrade to 6.0.3.
