Astra Linux – Vulnerability in Qemu

A flaw was discovered in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can result in the callback being fired later, thereby causing a use-after-free when using the channel. This vulnerability can be exploited by a malicious...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: NFS: Fixed potential buffer overflows in nfssysfslinkrpcclient. The name field is a char64 type, and the size of clnt-clprogram-name remains unknown. Invoking strcat directly will also lead to potential buffer overflows...
