Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: rtl818x: rtl8187: Fixed a potential buffer underflow in rtl8187rxcb. The rtl8187rxcb function calculates the RX descriptor header address by subtracting its size from the skbtailptr. However, it does not validate whether th...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: Do not exceed the ARM processor CPER record buffer. There is a logic within GHES/CPER that detects whether the sectionlength is too small, but it does not detect whether it is too large. Currently, if the firmware...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Tracing: Ring-buffer: A fix was made to check the length of events before using them. Check the length of events before adding them for accessing the next index in rbreaddatabuffer. Since this function is used to validate possibl...

Astra Linux – Vulnerability in Erlang

Inconsistent interpretation of HTTP requests: The “HTTP Request Smuggling” vulnerability in Erlang OTP inets httpd module allows for HTTP requests to be disguised. This vulnerability is associated with the program file lib/inets/src/httpserver/httpdrequest.erl and the routine...

Astra Linux – Vulnerability in gst-plugins-ugly1.0

GStreamer ASF Demuxer Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability, but the attack vectors may va...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: libceph: Prevent potential out-of-bounds reads in handleauthdone. Perform an explicit bounds check on payloadlen to avoid possible out-of-bounds accesses during the callout operation. idryomov: changelog...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/umad: Reject negative datalen in ibumadwrite ibumadwrite calculates datalen based on a user-controlled count and the MAD header sizes. When the user-defined MAD header size does not match the RMPP header length, datalen can...

Astra Linux – Vulnerability in Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, the length of Skipdata was not checked for bounds. As a result, a user-provided Skipdata callback could cause the csdisasm/csdisasmiter memcpy function to write more than 24 bytes into csinsn.bytes, leading to a heap buffe...

Astra Linux – Vulnerability in Python 3.11

When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially leading to Out-of-Memory errors or other types of...

Astra Linux – Vulnerability in libsoup3

There is a vulnerability related to request smuggling in LibSoup’s HTTP/1 header parsing logic. The soupmessageheaders.AppendCommon function in libsoup/soup-message-headers.c appends each header value unconditionally, without checking for duplicates or conflicting Content-Length fields. This allo...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcievent: Check the length of skb for an unknown CC opcode. In hcicmdCompleteevt, if the command completion event has an unknown opcode, we assume that the first byte of skb-data contains the return status. However, th...

Astra Linux – Vulnerability in Thunderbird

A malicious mail server could send malformed strings with negative lengths, causing the parser to read memory outside the buffer. If a mail server or the connection to a mail server were compromised, an attacker could cause the parser to malfunction, potentially crashing Thunderbird or leaking...

Astra Linux – Vulnerability in pyopenssl

pyOpenSSL is a Python wrapper around the OpenSSL library. Starting from version 22.0.0 and before version 26.0.0, if a user provided a callback for setcookiegeneratecallback and the returned cookie value was longer than 256 bytes, pyOpenSSL would cause an overflow of the buffer provided by OpenSS...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: can: gsusb: gsusbreceivebulkcallback: Check actuallength before accessing the header. The driver expects to receive a struct gshostframe in gsusbreceivebulkcallback. Use structgroup to describe the header of the struct gshostfram...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Fixed out-of-band OOB access during the parseadvmonitorpattern function execution. In the parseadvmonitorpattern function, the value of the length variable is currently limited to HCIMAXEXTADLENGTH251. The size o...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: can: gsusb: gsusbreceivebulkcallback: Check actuallength before accessing the data. The URB received in gsusbreceivebulkcallback contains a struct gshostframe. The length of the data after the header depends on the gshostframe...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: spi: fsl-cpm: Length parity checks were performed before switching to 16-bit mode. The commit fc96ec826bce “spi: fsl-cpm: Use 16-bit mode for large transfers with even size” failed to ensure that the size of the data transfer was...

Astra Linux – Vulnerability in pyasn1

pyasn1 is a generic ASN.1 library for Python. Prior to version 0.6.3, the pyasn1 library was vulnerable to a Denial of Service DoS attack caused by uncontrolled recursion during the decoding of ASN.1 data with deeply nested structures. An attacker could provide a crafted payload containing...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: Do not dump the entire memory region. The current logic in cperprintfwerr does not check whether the length of the error record is sufficient to handle the offset. In a faulty firmware, if the offset is greater than the...

nghttp2: nghttp2: HTTP Request/Response Smuggling and Response-Queue Poisoning via ambiguous HTTP/1.1 Upgrade requests

A flaw in nghttp2's nghttpx proxy allows a remote attacker to perform HTTP request smuggling and cross-client response-queue poisoning. This occurs because the proxy ambiguously forwards HTTP/1.1 Upgrade requests that contain a Content-Length header to reusable keep-alive backend connections...
