In the Linux kernel, the following vulnerabilities have been resolved: IB/hfi1: Fixed the “off-by-one” error in sdma.h’s tx-numdescs. Unfortunately, the commit fd8958efe877 introduced another error, causing the descp array to overflow. This leads to further crashes that can be easily reproduced...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in gnutls. There is an “off-by-one” error in the bounds check for the PKCS12 bag element. This vulnerability allows a remote attacker to write beyond the internal array of a PKCS12 bag when appending to a bag that already contains 32 elements. This memory corruption could le...

Astra Linux – Vulnerability in Tomcat9, libcommons-fileupload-java

Apache Commons FileUpload before version 1.5 does not limit the number of request parts that can be processed, which means that an attacker could potentially trigger a Denial-of-Service attack with a malicious upload or series of uploads. It’s important to note that, like all file upload...

Astra Linux – Vulnerability in Thunderbird

When loading the shared library that provides the OTR protocol implementation, Thunderbird initially attempts to open it using a filename that is not distributed by Thunderbird. If a computer has already been infected with a malicious library from the alternative filename, and the malicious libra...

Astra Linux – Vulnerability in elfutils

The libcpu component, which is used by libasm of elftools version 0.177 git 47780c9e, suffers from denial-of-service vulnerabilities caused by application crashes due to out-of-bounds write CWE-787, off-by-one errors CWE-193, and reachable assertions CWE-617. To exploit these vulnerabilities,...

Astra Linux – Vulnerability in Systemd

A “off-by-one” error issue was discovered in Systemd within the formattimespan function of the time-util.c file. An attacker could provide specific values for time and accuracy, resulting in a buffer overflow in formattimespan, which can lead to a Denial of Service...

Astra Linux – Vulnerability in libvirt

A “off-by-one” error flaw was discovered in the udevListInterfacesByStatus function in libvirt, where the number of interfaces exceeds the size of the names array. This issue can be reproduced by sending specially crafted data to the libvirt daemon, allowing an unprivileged client to perform a...

In the Linux kernel, the following vulnerability has been resolved: dmaengine: nbpfaxi: Fixed memory corruption in probe The nbpf-chan array is allocated earlier in the nbpfprobe function, and it contains “numchannels” elements. These three loops iterate one element further than they should,...

Astra Linux – Vulnerability in Tomcat9

A “off-by-one” error vulnerability in Apache Tomcat affects the N flag used for rewrite valves, causing rewrite processing to restart at the second rule instead of the first rule. This issue affects Apache Tomcat versions from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, and from...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ep93xx: clock: Fix for an offset of one in ep93xxdivrecalcrate. The psc-div array contains psc-numdiv elements. These values are derived from when we call clkhwregisterdiv. The size of these values is determined by...

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: w1: therm: Fixed an off-by-one buffer overflow in alarmsstore. The sysfs buffer passed to alarmsstore is allocated with ‘size + 1’ bytes, and a NUL terminator is appended. However, the ‘size’ argument does not account for this...

Astra Linux – Vulnerability in ldns

NLnet Labs’ ldns version 1.2.0, including versions up to and including 1.9.0, when used as a stub resolver over UDP, fails to match the query destination address and port with the response source address and port. Moreover, neither the query ID nor the nature of the query matches that of the...

Astra Linux – Vulnerability in NTP

In NTP versions prior to 4.2.8p14 and 4.3.x before 4.3.100, ntpd allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address. This occurs because transmissions are rescheduled even when a packet lacks a valid origin timestamp...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in the Linux kernel before version 6.3.4. In the fs/ksmbd/connection.c file of ksmbd, there is an off-by-one error in memory allocation due to ksmbdsmb2checkmessage, which may lead to out-of-bounds access...
