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

In the Linux kernel, the following vulnerabilities have been resolved: ELF: fixed the double read of kernel.randomizevaspace. The ELF loader uses “randomizevaspace” twice. This is a sysctl setting that can be changed at any time; therefore, two reads could potentially access different values,...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: PCI: Fixed the memory leak in resetmethodstore In resetmethodstore, a string is allocated via kstrndup and assigned to the local variable “options”. Then, options is used with strsep to find spaces: c while name = strsep&options,...

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: vsock: prevented null-ptr-deref in vsockhasdata|hasspace. Recent reports have shown that we sometimes call vsockhasdata when a vsock socket has been de-assigned from a transport see attached links. However, this should not be don...

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: vfio/platform: checking the bounds of read/write syscalls. The count and offset parameters are passed from user space without being checked. Only the offset parameter is capped at 40 bits, which can be used to read/write data...

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

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: A problem with uninitialized size values was fixed in radeonvcecsparse. In the unlikely event that the command stream passed from user space via ioctl calls to radeonvcecsParse is maliciously crafted, and the first...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xfrm: Zero padding when dumping algorithms and encap templates. When copying data to user-space, we must ensure that only valid data is copied. Padding in structures may contain random potentially sensitive data and should never ...

Astra Linux – Vulnerability in sane-backends

A out-of-bounds read in SANE backends before version 1.0.30 may allow a malicious device connected to the same local network as the victim to read important information, such as the ASLR offsets of the program, also known as GHSL-2020-081...

Astra Linux – Vulnerability in glibc

On the x86-64 architecture, the GNU C Library also known as glibc prior to version 2.31 fails to ignore the LDPREFERMAP32BITEXEC environment variable during program execution after a security transition. This allows local attackers to restrict the possible mapping addresses for loaded libraries,...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: PowerPC: Fixed virtaddrvalid for 64-bit Book3E & 32-bit systems. MPE: On 64-bit Book3E, the vmalloc space starts at 0x8000000000000000. Due to the way pa works, pa0x8000000000000000 returns 0. Consequently,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: btrfs: fixed a hang that occurred during unmount when stopping a space reclaim worker Often, when running the generic/562 test from fstests, a hang may occur during unmount, resulting in a log message like this: Sep 07 11:52:0...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: btrfs: Do not drop the extentmap for free space inode on a write error. While running the CI for an unrelated change, I encountered the following panic: with generic/648 on btrfsholesspacecache. Assertion failed: blockstart !=...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: tpm: use trygetops in tpm-space.c As part of the series of changes to remove nested TPM operations: https://lore.kernel.org/all/[email protected]/ The exposure of the chip-tpmmutex was removed...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fixed the potential underflow in virtiotransportgetcredit. The credit calculation in virtiotransportgetcredit uses unsigned arithmetic: ret = vvs-peerbufalloc - vvs-txcnt - vvs-peerfwdcnt; If the peer reduces its...

Astra Linux – Vulnerability in exempi

The XMP Toolkit SDK versions 2020.1 and earlier are affected by an out-of-bounds read vulnerability that could lead to the disclosure of arbitrary memory. An attacker could exploit this vulnerability to bypass security measures such as ASLR. Exploiting this issue requires user interaction, as the...

Astra Linux – Vulnerability in Jetty9

Eclipse Jetty Canonical Repository is the canonical repository for the Jetty project. Users of the CgiServlet with a very specific command structure may have the wrong command executed. If a user sends a request to an org.eclipse.jetty.servlets.CGI Servlet for a binary file whose name contains...
