Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtCT: Dropping pending packets that are enqueued during the removal of a template. “Templates” refer to objects that can disappear when packets are stored in nfqueue. nfqueue refers to: - helpers: This can be a issue...

Astra Linux – Vulnerability in OpenLDAP

A flaw was discovered in OpenLDAP in versions prior to 2.4.56. This flaw allows an attacker who sends a malicious packet processed by OpenLDAP to force a failed assertion in csnNormalize23. The greatest threat of this vulnerability is to system availability...

Astra Linux – Vulnerability in Linux 5.10

A double-free bug in the packetsetring function in net/packet/afpacket.c can be exploited by a local user through crafted syscalls to escalate privileges or deny services. We recommend upgrading the kernel to a version that is not affected by this bug, or rebuilding the code after the...

A vulnerability has been discovered in the Linux kernel. It has been classified as problematic. The affected function is nilfsnew inode in the file fs/nilfs2/inode.c of the BPF component. This vulnerability allows for manipulation after the memory allocation function free is called. The attack ca...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel in versions prior to 5.4.92 regarding the BPF protocol. This flaw allows an attacker with a local account to disclose information about kernel internal addresses. The greatest threat posed by this vulnerability relates to confidentiality...

Astra Linux – Vulnerability in Linux, Linux 5.10

A stack overflow flaw was discovered in the Linux kernel’s TIPC protocol functionality. This flaw occurs when a user sends a packet containing malicious content, where the number of domain member nodes exceeds the allowed limit of 64. This flaw allows a remote user to crash the system or...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: afpacket: fixed vlangetprotocoldgram vs MSGPEEK The responsible commit forgot to handle the MSGPEEK case, resulting in a crash 1, as detected by syzbot. vlangetprotocoldgram was rewritten so that it does not touch the skb at...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed an issue in verifying allowptrleaks. After we changed the capabilities of our networking-bpf program from capsysadmin to capnetadmin+capbpf, our networking-bpf program failed to start. This was because it failed the bp...

Astra Linux – Vulnerability in Wireshark
