Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: initialize registers in nftdochain The registers were initialized to prevent a stack leak into the user space...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sched/scs: The task stack state is reset in bringupcpu. When a CPU is hot-plugged, the idle task on that CPU calls several layers of C code before finally leaving the kernel. When KASAN is in use, a “poisoned” shadow is left behi...

Astra Linux – vulnerability in libxstream-java

XStream serializes Java objects to XML and back again. Versions prior to 1.4.20 may allow a remote attacker to terminate the application via a stack overflow error, resulting in a denial of service by manipulating the processed input stream. The attack exploits the hash code implementation for...

Astra Linux – vulnerability in libjettison-java

A stack overflow in Jettison prior to version 1.5.2 enables attackers to trigger a Denial of Service DoS condition by using specially crafted JSON data...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkosf: fixed a possible incorrect match in nfosffind. nfosffind incorrectly returns true in case of a mismatch, which leads to copying uninitialized memory areas in nftosf. This can result in leaking stale kerne...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fixed pointer-leak due to insufficient speculative store bypass mitigation To mitigate Spectre v4, the patch 2039f26f3aca “bpf: Fixed leakage due to insufficient speculative store bypass mitigation” includes instructions...

Astra Linux – Vulnerability in libcroco

In libcroco version 0.6.13, there is excessive recursion in the cr parser function cr parserparseanycore in cr-parser.c, resulting in stack consumption...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: BPF, sockmap: Do not allow sockmapclose,destroy,unhash to call itself. Proto callback functions in sockmap should never call themselves by design. Protect against bugs like 1 and break out of the recursive loop to avoid a stac...

Astra Linux – vulnerability in exempi

The XMP Toolkit SDK version 2020.1 and earlier is affected by a stack-based buffer overflow vulnerability that could potentially lead to arbitrary code execution in the context of the current user. Exploitation requires user interaction; a victim must open a specially crafted file...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Prevent stack buffer overflow caused by kernel command line Although the kernel command line is considered trusted in most environments, be cautious of writing 1 byte beyond the end of “acpiid” when the “str” argument...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: riscv: stacktrace: Disable KASAN checks for non-current tasks When unwinding the stack of a task other than the current one, KASAN would report “BUG: KASAN: out-of-bounds in walkstackframe+0x41c/0x460” The same issue exists on x8...

Astra Linux – vulnerability in zeromq3

A flaw was found in the ZeroMQ server in versions prior to 4.3.3. This flaw enables a malicious client to trigger a stack buffer overflow on the server by sending specially crafted topic subscription requests followed by unsubscription. The primary risks associated with this vulnerability are...

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

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: dccp: copying the entire header to the stack buffer, not just the basic header Eric Dumazet states that: nfconntrackdccppacket has a unique mechanism: dh = skbheaderpointerskb, dataoff, sizeofdh, &dh; And...

Astra Linux – Vulnerability in exempi

The XMP Toolkit SDK version 2021.07 and earlier is affected by a stack-based buffer overflow vulnerability that may lead to arbitrary code execution within the context of the current user. Exploitation requires user interaction—that is, the victim must open a specially crafted file...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: iio: adc: ti-adc161s626: use DMA-safe memory for spiread Add a DMA-safe buffer and use it for spiread instead of stack memory. All SPI buffers must be DMA-safe. Since we only need up to 3 bytes, we simply use a u8 instead of be16...

Astra Linux – vulnerability in gst-plugins-base1.0

In GStreamer up to version 1.26.1, the parsesubriptime function in the subparse plugin may write data beyond the bounds of a stack buffer, resulting in a crash...

Astra Linux – vulnerability in libde265

Libde265 v1.0.8 was found to contain a stack buffer overflow vulnerability in fallback-motion.cc via putqpelfallback. This vulnerability enables attackers to trigger a Denial of Service DoS condition by using a specially crafted video file...

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...
