Astra Linux – Vulnerability in gst-plugins-base1.0

GStreamer is a library for constructing graphs of media-handling components. A stack-buffer overflow has been detected in the gstopusdecparseheader function within gstopusdec.c. The pos array is a stack-allocated buffer of size 64. If nchannels exceeds 64, the for loop will write beyond the...

Astra Linux – Vulnerability in Zabbix

When a URL is added to the map element, it is recorded in the database with a sequential ID. When adding a new URL, the system retrieves the previous value of the sysmapelementurlid and increments it by one. However, an issue arises when a user manually changes the sysmapelementurlid value by...

Astra Linux – Vulnerability in Firefox and Thunderbird

A malicious website that could create a popup might resize the popup to overlay the address bar with its own content, causing potential confusion for users or leading to spoofing attacks. This bug only affects Thunderbird for Linux. Other operating systems are unaffected.. This vulnerability...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ipv6/addrconf: fixed a potential refcount underflow for idev. In addrconfmodrstimer, the reference to idev depends on whether rstimer is not pending. Therefore, the timeout of rstimer was modified. There is a time gap in 1 during...
