Apple

Apple has released security updates for three of its software products: iTunes for Windows, iCloud for Windows and iOS. These updates patch major vulnerabilities in software components in these products. Vulnerabilities include memory corruption issues, input validation flaws, and out-of-bounds reads that could lead to remote code execution (RCE), privilege escalation or information disclosure (ID).

The latest version of both iTunes for Windows (12.9.5) and iCloud for Windows (7.12) is now available for Windows 7 and subsequent versions. Likewise, iOS 12.3.1 is available for iPhone 5s and later, iPad Air and later, and iPod touch 6th generation. Apple users are advised to update to these new versions.

Cisco

Cisco has published security advisories to address multiple vulnerabilities in NX-OS, FXOS and Cisco’s Secure Boot implementation. Among them, two flaws were rated as high-impact. CVE-2019-1649, found in Secure Boot, was the result of an incorrect code present in the implementation, that could lead to attackers write modified firmware images in Secure Boot. Similarly, CVE-2019-1858, found in Simple Network Management Protocol (SNMP) of FXOS and NXOS could enable attackers to put devices in a denial-of-service (DoS) condition.

Software updates have been released by Cisco to resolve all these vulnerabilities. Users are advised to apply these updates soon.
