Astra Linux – Vulnerability in mbedtls

In Mbed TLS versions prior to 2.28.10, and 3.x versions prior to 3.6.3, on the client side, servers with trusted certificates for arbitrary hostnames are accepted, unless the TLS client application calls mbedtlssslsethostname...

Astra Linux – Vulnerability in Perl

HTTP::Tiny, a Perl core module since version 5.13.9 and available as a standalone package on CPAN, has an insecure default TLS configuration. In this configuration, users are required to explicitly choose to verify certificates...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net/tls: fixed a kernel panic that occurred when allocpage failed. We cannot set fraglist to a NULL pointer when allocpage fails. This setting will be used in tlsstrpcheckqueueok when tlsstrpreadsock is called next time. This ...

Astra Linux – Vulnerability in Linux 5.10, Linux

There is a use-after-free vulnerability in the Linux Kernel that can be exploited to achieve local privilege escalation. To exploit this vulnerability, the CONFIGTLS or CONFIGXFRMESPINTCP kernel configuration flags must be set; however, the operation does not require any special privileges. There...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Mbed TLS before version 2.25.0 and before versions 2.16.9 LTS and 2.7.18 LTS. The calculations performed by mbedtlsmpiexpmod are not limited; therefore, providing overly large parameters could lead to a denial of service when generating Diffie-Hellman key pairs...

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

The dotlsgetsockopt function in net/tls/tlsmain.c in the Linux kernel, up to version 6.2.6, lacks a locksock call, resulting in a race condition. This can lead to a use-after-free issue or a NULL pointer dereferencing...

Astra Linux – Vulnerability in Apache2

In some modssl configurations on the Apache HTTP Server 2.4.35 to 2.4.63, it is possible for trusted clients to bypass access controls using TLS 1.3 session resumption. These configurations are affected when modssl is configured for multiple virtual hosts, with each virtual host restricted to a...

Astra Linux – Vulnerability in curl

When performing multi-threaded LDAPS transfers LDAP over TLS with libcurl, changing TLS options in one thread will inadvertently change them globally, and thus may also affect other concurrently running transfers. Disabling certificate verification for a specific transfer can unintentionally...

Astra Linux – Vulnerability in syslog-ng

syslog-ng is an enhanced logging daemon. Prior to version 4.8.2, the tlswildcardmatch function matched against certificates like foo..bar, although this is not allowed. It is also possible to pass partial wildcards, such as foo.ac.bar, which glib logs match, but this should be avoided/disabled...

Astra Linux – Vulnerability in Wireshark

The TLS protocol dissector heap overflow in Wireshark versions 4.6.0 to 4.6.4 allows for denial of service attacks, and may lead to code execution...

Astra Linux – Vulnerability in Wireshark

The TLS ECH decryptor module crashes in Wireshark versions 4.6.0 to 4.6.6, allowing denial of service attacks...

Astra Linux – Vulnerability in Node.js

A malformed HTTP/2 HEADERS frame with oversized, invalid HPACK data can cause Node.js to crash by triggering an unhandled TLSSocket error ECONNRESET. Instead of safely closing the connection, the process crashes, enabling a remote denial of service. This primarily affects applications that do not...

Astra Linux – Vulnerability in mbedtls

A vulnerability was discovered in Mbed TLS before versions 2.28.1 and 3.x, prior to 3.2.0. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server, causing a heap-based buffer overflow of up to 255 bytes. This can lead to a server crash or,...

Astra Linux – Vulnerability in mbedtls

Integer overflow vulnerability in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2. Attackers can exploit this vulnerability to cause a denial of service DoS attack through the mbedtlsx509setextension function...

Astra Linux – Vulnerability in Firefox

If the user adds a security exception for an invalid TLS certificate, opens an ongoing TLS connection with a server that uses that certificate, and then deletes the exception, Firefox will keep the connection alive, making it appear that the certificate is still trusted. This vulnerability affect...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Arm Mbed TLS before version 2.24.0. It incorrectly uses a revocationDate check when deciding whether to honor certificate revocation via a CRL. In some situations, an attacker can exploit this by changing the local clock...

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

In the Linux kernel, the following vulnerability has been resolved: Networks: TLS – Avoid hanging tasks when using txlock. The syzbot reported a situation where tasks were hung. Eric explains that the adversarial receiver may keep RWIN at 0 for a long time, so we cannot guarantee progress. Thread...

Astra Linux – Vulnerability in openjdk-11

Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE component: JSSE. The supported versions affected are Java SE: 7u311, 8u301, 11.0.12; Oracle GraalVM Enterprise Edition: 20.3.3 and 21.2.0. This easily exploitable vulnerability allows an unauthenticated...

Astra Linux – Vulnerability in OpenSSL

Issue Summary: Some non-default TLS server configurations can cause unbounded memory growth when processing TLSv1.3 sessions. Impact Summary: Attackers may exploit certain server configurations to trigger unbounded memory growth, leading to a Denial of Service attack. This issue can occur 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: BPF, ktls: Fixed data corruption when using bpfmsgpopdata in ktls. When sending plaintext data, we initially calculated the corresponding ciphertext length. However, if we later reduce the plaintext data length via socket...
