An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/V

[HIGH] Vulnerability Spotlight: Asus router access, information disclosure, denial of service vulnerabilities discovered
## Vulnerability Spotlight: Asus router access, information disclosure, denial of service vulnerabilities discovered
Cisco Talos recently discovered three vulnerabilities in Asus router software.
The Asus RT-AX82U router is one of the newer Wi-Fi 6 (802.11ax)-enabled routers that also supports mesh networking with other Asus routers. Like other routers, it is configurable via an HTTP server running on the local network. However, it can also be configured to support remote administration and monitoring in more of an IOT style.
Talos has identified TALOS-2022-1586 (CVE-2022-35401), an authentication bypass vulnerability that can lead to full administrative privileges. An attacker would need to send a series of HTTP requests to exploit this vulnerability.
