Less than two weeks after patching a dangerous flaw in PAN-OS operating system Palo Alto Networks has released security upd ate which addresses another severe vulnerability in PAN-OS devices.

The new issue, tracked as CVE-2020-2034, is an OS Command Injection vulnerability impacting the PAN-OS GlobalProtect which could be exploited by an unauthenticated network-based attacker to execute arbitrary OS commands with root privileges.

Apart from the above mentioned vulnerability, the vendor also fixed several less dangerous flaws (CVE-2020-2031, CVE-2020-2030, CVE-2020-1982) that allow a remote attacker to decrypt TLS traffic, execute arbitrary commands, or launch DoS attacks.

Citrix released security updates to address a se t of 11 vulnerabilities affecting its Citrix ADC, Citrix Gateway, and Citrix SD-WAN WANOP (appliance models 4000-WO, 4100-WO, 5000-WO, and 5100-WO) networking products. One of the flaws (CVE-2020-8194) could be exploited for remote code execution, while others could result in information disclosure or could allow a remote user to escalate privileges on the system.

A couple of high risk vulnerabilities have been found in Chocolate Doom (CVE-2020-14983) and Crispy Doom (CVE-2020-14983) that can be used by a remote attacker to execute arbitrary code on a target system.

TCP/IP function included in the firmware of Mitsubishi Electric GOT2000 series GT27, GT25, and GT23 contains multiple vulnerabilities. The most severe of them are a buffer overflaw issue (CVE-2020-5595), which may allow a remote attacker to stop the network functions of the products or execute a malicious program via a specially crafted packet, and CVE-2020-5598, which could be exploited by a remote attacker to gain unauthorized access to otherwise restricted functionality.

OpenClinic GA, an open-source integrated hospital information management system contains a dozen vulnerabilities with three of them rated as high risk flaws (CVE-2020-14487, CVE-2020-14495, CVE-2020-14485) that could be exploited to bypass authentication process or completely compromise a vulnerable system.

FFmpeg 4.2.3 has a vulnerability, which allow to compromise vulnerable system. The flaw exists due a use-after-free error in FFmpeg when processing a crafted EXTINF duration in an m3u8 file because parse_playlist in libavformat/hls.c frees a pointer, and later that pointer is accessed in av_probe_input_format3 in libavformat/format.c.

A remote code execution vulnerability has been found in the Zoom client for Windows that allows to compromise vulnerable system. The good news is that the flaw has a couple of mitigating factors - it is only exploitable on systems running Windows 7 and older versions of the OS that are no longer supported by Microsoft, and the attack requires user interaction.
