Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfrailserverexecuteresult indexed the global errorcodenames array 7 elements, indices 0–6 using an unchecked execResult-execResult value received from the server. This led to a potential out-of-bounds read...

In the Linux kernel, the following vulnerability has been resolved: ipv6: Annotated data-race in ndiscrouterdiscovery The syzbot found that ndiscrouterdiscovery could read and write in6dev-ramtu without holding a lock 1 This seems fine, as IFLAINET6RAMTU is a best-effort mechanism. Add...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a heap-buffer overflow occurred during drive reads when a server-controlled read length was used to read file data into an IRP output stream buffer without a hard upper limit. This allowed an oversized read ...

In the Linux kernel, the following vulnerability has been resolved: media: adv7842: Avoid possible out-of-bounds array accesses in adv7842cplogstatus It is possible for cpread and hdmiread to return -EIO. These values are further used as indexes to access arrays. The issue was fixed by checking t...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh, where a malicious SFTP SSH File Transfer Protocol server can exploit this by sending a malformed ‘longname’ field within an SSHFXPNAME message during a file listing operation. This missing null check can lead to reading beyond the allocated memory on the heap. Thi...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, the URBDRC client used server-supplied interface numbers as array indices without bounds checks, resulting in a out-of-bounds read in libusbudevselectinterface. This vulnerability has been fixed in version...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: md: fixed rcu protection in mdwakeupthread We attempted to use RCU to protect the pointer “thread”, but passed the value directly when calling mdwakeupthread. This means that the RCU pointer was acquired before rcureadlock was...

Astra Linux – Vulnerability in libssh

A vulnerability has been identified in libssh up to version 0.11.3. The affected element is the function sftpextensionsgetname/sftpextensionsgetdata in the file src/sftp.c of the SFTP Extension Name Handler component. Performing operations on the argument idx can lead to out-of-bounds read...
