Google-owned threat intelligence company Mandiant later claimed that the vulnerability has been exploited for nearly a year in attacks targeting companies and critical infrastructure.
The Google Android March security bulletin includes fixes for more than 50 security issues. The most severe is a critical vulnerability in the System component that could lead to remote code execution with no additional execution privileges needed. User interaction is not required for exploitation, Google said.
Google also patched eight issues in the Framework marked as having a high severity, which could lead to privilege escalation without any user interaction.
Meanwhile, researchers at Google’s Project Zero have reported 18 zero-day vulnerabilities in Exynos Modems
Affected devices include those in the S22, M33, M13, M12, A71, A53, A33, A21s, A13, A12, and A04 series, as well as Google’s Pixel 6 and Pixel 7 series.
Patch timelines will vary per manufacturer, but affected Pixel devices have received a fix for all four of the severe internet-to-baseband remote code execution vulnerabilities. In the meantime, users with affected devices can protect themselves by turning off Wi-Fi calling and Voice-over-LTE (VoLTE) in their device settings, Google said.
Google has released Chrome 111 of its popular browser, fixing eight security flaws, seven of which are memory safety bugs with a high severity rating. Four use-after-free vulnerabilities include a high-severity issue tracked as CVE-2023-1528
Meanwhile, CVE-2023-1530 is a use-after-free bug in PDF reported by the UK’s National Cyber Security Centre, and CVE-2023-1531 is a high-severity use-after-free vulnerability in ANGLE.
None of the issues are known by Google to have been used in attacks, but given their impact, it makes sense to update Chrome when you can.
Enterprise software giant Cisco has published the twice-yearly security bundle for its IOS and IOS XE Software, fixing 10 vulnerabilities. Six of the issues fixed by Cisco are rated as having a high impact, including CVE-2023-20080, a denial of service flaw, and CVE-2023-20065, a privilege escalation bug.
At the start of the month, Cisco fixed multiple vulnerabilities in the web-based management interface of some Cisco IP Phones that could allow an unauthenticated, remote attacker to execute arbitrary code or cause denial of service. With a CVSS score of 9.8, the worst is CVE-2023-20078, a vulnerability in the web-based management interface of Cisco IP Phone 6800, 7800, and 8800 series multiplatform phones.
