Astra Linux – Vulnerabilities in Firefox, LibWebP, Thunderbird

There exists a use after free/double free in libwebp. An attacker can use the ApplyFiltersAndEncode function and loop through to free the best.bw file, assigning the best pointer to trial. The second loop will then return 0 due to a memory out-of-memory error in the VP8 encoder; the pointer remai...

Astra Linux – Vulnerability in Linux

Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in orde...

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 – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ceph: Avoid putting the realm twice when decoding snaps fails. When decoding snaps fails, it may leave the 'firstrealm' and 'realm' pointers pointing to the same snaprealm memory. Doing so could lead to random use-after-free...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Nosy driver within the Linux kernel. This issue allows a device to be inserted twice into a doubly-linked list, resulting in a “use-after-free” condition when one of these devices is removed. The most significant threat posed by this vulnerability relates to...
