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 u-boot

A issue was discovered in Das U-Boot during the period from 2019.07. There is an unbounded memcpy operation with a failed length check at nfsreadreply, when calling storeblock in the NFSv2 case...

Astra Linux – Vulnerability in ruby-loofah

Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah = 2.2.0; versions before 2.19.1 use recursion to sanitize CDATA sections, which can lead to stack exhaustion and raise a SystemStackError exception. This may result in ...

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: bnxten: Correctly sets the DMA unmap len for XDPREDIRECT. When transmitting an XDPREDIRECT packet, call dmaunmaplenset with the correct length instead of 0. This bug triggers this warning on a system with IOMMU enabled: WARNIN...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: The length of the packet header is validated before calling skbPut. When receiving a vsock packet in the guest, only the size of the virtqueue buffer is validated prior to calling virtiovsockskbrxPut. Unfortunately,...

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

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Added a length limitation for the ivrsacpihid command-line parameter. The acpiid buffer in the parseivrsacpihid function may overflow, because the string specifier in the fscan function lacks a width limitation. Found ...

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 found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: - In pptp: ensure that the minimum skb length is properly set in pptpxmit. - Commit aabc6596ffb3 “net: ppp: Add bound checking for skb data in pppsynctxmung” fixed pppsynctxmunge. We need a similar fix in pptpxmit; otherwise, ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: A bug in accessing the uninit variable was fixed in qrtrtxresume. Syzbot reported the bug as follows: ===================================================== Bug: KMSAN: Access to the uninitvalue variable in...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the X Record extension. The RecordSanityCheckRegisterClients function does not check for an integer overflow when calculating the request length, allowing a client to bypass the length checks...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: zonefs: fixed zonefsiomapbegin for reads. If a readahead operation is issued on a sequential zone file with an offset that exactly equals the current file size, the iomap type is set to IOMAPUNWRITTEN, which will prevent any I/O...

Astra Linux – Vulnerability in u-boot

A issue was discovered in Das U-Boot during the period from 2019.07. There is an unbounded memcpy operation with an unvalidated length at nfsreadlinkreply, located in the “if” block, after calculating the new path length...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: i2c: tegra: check msg length in SMBUS block read For SMBUS block read, do not continue reading if the message length passed from the device is ‘0’ or greater than the maximum allowed bytes...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU virtual crypto device during handling of data encryption/decryption requests in virtiocryptohandlesymreq. There is no check for the values of srclen and dstlen in virtiocryptosymophelper, which may lead to a heap buffer overflow if these values differ...

Astra Linux – Vulnerability in grub2

The “read” command is used to read the keyboard input from the user. While reading, the input length is stored as a 32-bit integer value. This value is then used to reallocate the line buffer to accommodate the next character. During this process, if the line is long enough, it’s possible for thi...

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

In the Linux kernel, the following vulnerability has been resolved: comedi: A flaw in the comedibufmunge function was addressed. This function performs a modulo operation async-mungechan %= async-cmd.chanlistlen, without first checking whether chanlistlen is zero. If a user program submits a...

Astra Linux – Vulnerability in Firefox

An attacker could have written a value to the first element of a zero-length JavaScript array. Although the array was zero-length, the value was not written to an invalid memory address. This vulnerability affects Firefox versions earlier than 104...
