Astra Linux – Vulnerability in Wireshark

In Wireshark versions 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the WiMax DLMAP dissector could crash. This issue was addressed in the plugin plugins/epan/wimax/msgdlmap.c by validating the length field...

Astra Linux – Vulnerability in ruby-loofah

Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah = 2.2.0; versions before 2.19.1 use recursion to sanitize CDATA sections, which can lead to stack exhaustion and raise a SystemStackError exception. This may result in ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: virtio-net: Ensure that the received length does not exceed the allocated size.
