Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

HighActively exploited

An integer overflow issue in Apple systems, fixed in Security Update 2021-005 Catalina, iOS 14.8 and iPadOS 14.8, macOS Big Sur 11.6, and watchOS 7.6.2, may lead to arbitrary code execution when processing a maliciously crafted PDF. Apple is aware of active exploitation.

CVE-2021-30858
HighActively exploited

A use-after-free vulnerability in WebKit, fixed by improved memory management. Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.

CVE-2021-39144
HighActively exploited

XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker with sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.

CVE-2021-35395
CriticalActively exploited

Realtek Jungle SDK versions v2.x through v3.4.14B includes an HTTP web server exposing a management interface (webs or boa) that is affected by multiple stack buffer overflows and arbitrary command execution flaws. The issues occur in functions such as formRebootCheck, formWsc, formWlanMultipleAP, formWlSiteSurvey, formStaticDHCP, and formSysCmd due to unsafe copying of parameters like submit-url, ifname, hostname, peerPin, and sysCmd. Successful exploitation allows remote attackers to achieve arbitrary code execution on the device.

CVE-2021-35394
CriticalActively exploited

Realtek Jungle SDK version v2.x up to v3.4.14B provides a diagnostic tool called 'MP Daemon' that is usually compiled as 'UDPServer' binary. The binary is affected by multiple memory corruption vulnerabilities and an arbitrary command injection vulnerability that can be exploited by remote unauthenticated attackers.

CVE-2021-26086
MediumActively exploited
