Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in KVM AMD Secure Encrypted Virtualization SEV within the Linux kernel. A KVM guest that uses SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the VMGEXIT handler recursively. If an attacker manages to call the handler...

Astra Linux – Vulnerability in openimageio

A stack-based buffer overflow vulnerability exists in the TGA file format parser of OpenImageIO v2.3.19.0. A specially crafted targa file can lead to out-of-bound read and write operations on the process stack, which can result in arbitrary code execution. An attacker can provide a malicious file...

Astra Linux – Vulnerability in binutils

A issue was discovered in cp-demangle.c within GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption problem caused by the cplusdemangletype function making recursive calls to itself in certain scenarios involving many ‘P’ characters...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf, verifier: Fixed a memory leak in array reallocation for stack state. If an error NULL is returned by krealloc, callers of reallocarray would set their allocation pointers to NULL. However, when an error occurs in krealloc, i...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/tcp-ao: The comparison of MACs has been fixed to be at constant time. To prevent timing attacks, MACs need to be compared at constant time. Use the appropriate helper functions for this purpose...

Astra Linux – Vulnerability in dpdk

NVIDIA’s distribution of the Data Plane Development Kit MLNXDPDK contains a vulnerability in the network stack, where error recovery is not handled properly. This vulnerability can allow a remote attacker to cause denial of service, as well as affect data integrity and confidentiality...

Astra Linux – Vulnerability in Qemu

A stack-based buffer overflow was discovered in the virtio-net device of QEMU. This issue occurs when flushing the TX operation in the virtionetflushtx function, provided that the guest has enabled VIRTIONETFHASHREPORT, VIRTIOFVERSION1, and VIRTIONETFMRGRXBUF. This could allow a malicious user to...
