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: Wifi: mac80211: ocb: skipping RXnosta when the interface is not joined The ieee80211ocbrxnosta function assumes a valid channel context, which is only present after the JOINOCB operation. RX operations may occur before JOINOCB is...

Astra Linux – Vulnerability in zsh

In Zsh before version 5.8, attackers who were able to execute commands could regain privileges lost due to the --no-PRIVILEGED option. Zsh failed to overwrite the saved user ID, so the original privileges could be restored by executing MODULEPATH=/dir/with/module zmodload with a module that calls...

Astra Linux – Vulnerability in grub2

A vulnerability related to operations after freeing memory has been discovered in GRUB’s gettext module. This flaw arises from a programming error where the gettext command remains registered in memory even after its associated module is unloaded. An attacker can exploit this condition by invokin...

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: igb: A potential invalid memory access issue has been fixed in igbinitmodule. The pciregisterdriver function may fail. When this occurs, the dcanotifier needs to be unregistered. Otherwise, the dcanotifier can be called when igb...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net: macb: fixed the use of “free” after calling “rmmod”. “platdev-dev-platformdata” is released by calling “platformdeviceunregister”. The use of “pclk” and “hclk” constitutes a use-after-free. Since “deviceunregister” does n...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ublk: The kernel-owned devinfo fields are reset in the ublkctrladddev function. The memcpy function copies the ublksrvctrldevinfo from the user space into ub-devinfo, and then updates the fields owned by the driver. However, i...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free software available as a ready-to-run binary distribution or as source code that you can use, copy, modify, and distribute in both open and proprietary applications. In affected versions, Postscript files may be read and written when specifically excluded by a module policy in...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/slabcommon: fix slabcaches list corruption after kmemcachedestroy After the commit in Fixes:, if a module that created a slab cache does not release all of its allocated objects before destroying the cache at rmmod time, we...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ipack: ipoctal: fix module reference leak A reference to the carrier module was taken every time it was used, but it was only released once, when the final reference to the tty struct was removed. This issue was fixed by taking t...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In the proc subsystem, the same handling is used for checking proclseek as for procreaditer and others. Directly checking pde-procops-proclseek may lead to a Use-After-Value UAF in the rmmod scenario. This issue arises from a fla...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: tcp: Fix tcpinittransfer so that icskcainitialized is not reset. This commit fixes a bug identified by syzkaller that could cause spurious double-initializations for congestion control modules. This could lead to memory leaks or...

Astra Linux – Vulnerability in Ansible

A flaw was discovered in the solariszone module from the Ansible Community modules. When setting the name of a zone on the Solaris host, the zone name is checked by listing the process using the ‘ps’ command on the remote machine. An attacker could exploit this flaw by creating a fake zone name a...

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

In the Linux kernel, the following vulnerabilities have been resolved: Tracing: Build event generation tests are now performed only as modules. The kprobes and synth event generation test modules add events and lock them get a reference to those event files in the module initialization function,...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel 6.0.8, there is a use-after-free in the rununpack function in fs/ntfs3/run.c, which is related to a difference between the NTFS sector size and the media sector size...

Astra Linux – Vulnerability in libdata-validate-ip-perl

The Data::Validate::IP module in Perl version 0.29 does not properly handle extra zero characters at the beginning of an IP address string. In some cases, this allows attackers to bypass access controls that are based on IP addresses...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: staticcall: Replace the unnecessary WARNON call in staticcallmodulenotify. staticcallmodulenotify triggers a WARNON when memory allocation fails in staticcalladdmodule. This approach isn’t really justified, because the failure ca...

Astra Linux – Vulnerability in Samba

The Samba vfsfruit module utilizes extended file attributes EA, xattr to enhance compatibility with Apple SMB clients and interoperability with Netatalk 3 AFP file servers. Samba versions prior to 4.13.17, 4.14.12, and 4.15.5, when vfsfruit was configured, allowed out-of-bounds heap read and writ...

Astra Linux – Vulnerability in xrdp

xrdp is an open-source RDP server. Versions up to 0.10.5 contain a heap-based buffer overflow vulnerability in the NeutrinoRDP module. When proxying RDP sessions from xrdp to another server, the module fails to properly validate the size of reassembled fragmented virtual channel data against its...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: staticcall: Properly handle module initialization failures in staticcalldelmodule. Module insertion invokes staticcalladdmodule to initialize the static calls within a module. staticcalladdmodule calls staticcallinit, which...
