Astra Linux – Vulnerability in Linux

In the file drivers/pci/hotplug/rpadlpar/sysfs.c within the Linux kernel up to version 5.11.8, the RPA PCI Hotplug driver suffers a user-tolerable buffer overflow when writing a new device name to the driver from user space. This allows user space to write data directly to the kernel stack frame...

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

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: conntrack – removed the use of sprintf. Replace it with scnprintf; the buffer sizes should be large enough to hold the result, eliminating the need for checks related to snprintf and overflow. Increase the buffer si...

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: scs: A wrong parameter was fixed in scsmagic. The scsmagic function requires a void variable, but a struct taskstruct is provided instead. taskscstsk represents the starting address of the task’s shadow call stack, and...

Astra Linux – Vulnerability in Linux 5.15

In the efirtasmwrapper of efi-rt-wrapper.S, there is a possible way to bypass shadow stack protection due to a logical error in the code. This could result in a local escalation of privileges without the need for additional execution privileges. User interaction is not required for exploitation...

Astra Linux – Vulnerability in Corosync

Corosync versions up to 3.1.9 suffer from a stack-based buffer overflow in the orftokenendianconvert function, in the exec/totemsrp.c file. This vulnerability exists when encryption is disabled or if the attacker knows the encryption key. The issue is caused by a large UDP packet...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nftables: prefer nftchainvalidate nftchainvalidate already performs loop detection, as a cycle in the process could lead to a call stack overflow ctx-level = NFTJUMPSTACKSIZE. It also iterates through the maps via t...

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

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed an out-of-bounds write in triegetnextkey The triegetnextkey function allocates a node stack with a size of trie-maxprefixlen. However, it writes trie-maxprefixlen + 1 nodes to the stack when the stack is full, after...

Astra Linux – Vulnerability in vorbis-tools

A buffer underflow vulnerability has been identified in the ogg123 utility from the vorbis-tools 1.4.3 package, within the remotethread function in remote.c. This vulnerability occurs during the remote control functionality, when processing malformed inputs, resulting in a buffer underflow that c...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RISCV: Kernel mappings of the EFI page table must be synchronized before switching to the EFI page table. The EFI page table is initially created as a copy of the kernel page table. When VMAPSTACK is enabled, kernel stacks are...

Astra Linux – Vulnerability in Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, a unchecked return from vsnprintf in SStreamconcat allowed a malicious csoptmem.vsnprintf to manipulate SStream’s index beyond its limit, resulting in a stack buffer underflow/overflow when the next write operation occurre...

Astra Linux – Vulnerability in Apache2

Apache HTTP Server versions 2.4.0 to 2.4.46: A specially crafted Digest nonce can cause a stack overflow in modauthdigest. There is no report of this overflow being exploitable, nor can the Apache HTTP Server team have created such a report. However, certain compilers and/or compilation options...

Astra Linux – Vulnerability in Cairo

A flaw was discovered in cairo’s image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo’s image-compositor for example, by convincing a user to open a file in an application that uses cairo, or if an application uses cairo on...
