Astra Linux – Vulnerability in curl

libcurl will reuse a previously established connection even when options related to TLS or SSH have been changed, which should prevent such reuses. libcurl stores previously used connections in a connection pool, allowing for reuse if one of them matches the current setup. However, several TLS an...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: - net: tls: fixed a use-after-free issue related to partial reads and async decryption. tlsdecryptsg does not take a reference to the pages from clearskb; therefore, the putpage function in tlsdecryptdone releases those pages...

Astra Linux – Vulnerability in Apache2

Insufficient escaping of user-supplied data in modssl in Apache HTTP Server 2.4.63 and earlier allows an untrusted SSL/TLS client to insert escape characters into log files in some configurations. In a logging configuration where CustomLog is used with "%varnamex" or "%varnamec" to log variables...

Ivanti Connect Secure - Stack-based Buffer Overflow

Ivanti Connect Secure 22.7R2.5, Ivanti Policy Secure 22.7R1.2, and Ivanti Neurons for ZTA gateways 22.7R2.3 contain a stack-based buffer overflow in the clientCapabilities parameter handling. This vulnerability allows remote unauthenticated attackers to execute arbitrary code through IF-T TLS...

In the Linux kernel, the following vulnerabilities have been resolved: tls: fixed the missing memory barrier in tlsinit In tlsinit, a write memory barrier is missing, and store-store reordering may cause NULL dereferencing in tlssetsockopt,getsockopt. CPU0 CPU1 ----- ----- // In tlsinit // In...

Astra Linux – Vulnerability in Erlang

In Erlang/OTP versions prior to 23.3.4.15, 24.x before 24.3.4.2, and 25.x before 25.0.2, there was a situation where Client Authentication Bypass occurred in certain client-certification scenarios for SSL, TLS, and DTLS...

Astra Linux – Vulnerability in curl

When curl version 7.20.0 or later connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can send multiple responses at once, which are cached by curl. In this case, curl upgrades to TLS, but it does not discard the cached responses. Instead, it...

The supported versions affected by this vulnerability include Oracle Java SE: 8u361, 8u361-perf, 11.0.18, 17.0.6, 20; Oracle GraalVM Enterprise Edition: 20.3.9, 21.3.5, and 22.3.1...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/tls: The bug related to slab-out-of-bounds condition in decryptinternal has been fixed. The memory size of tlsctx-rx.iv for AES128-CCM is 12 bytes when tlssetswoffload is called. The return value of cryptoaeadivsize for...

Astra Linux – Vulnerability in Tomcat9

Apache Tomcat versions 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43, and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop, resulting in a denial of...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1, Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: tls: handling of backlogging of crypto requests Since we are setting the CRYPTOTFMREQMAYBACKLOG flag on our requests to the crypto API, cryptoaeadencrypt,decrypt can return -EBUSY instead of -EINPROGRESS in valid situations...

Astra Linux – Vulnerability in OpenSSL

AES OCB mode for 32-bit x86 platforms, using the AES-NI assembly-optimized implementation, may not encrypt all of the data under certain circumstances. This could reveal sixteen bytes of data that were already present in the memory but were not written. In the special case of “in-place” encryptio...

Astra Linux – Vulnerability in curl

There is a vulnerability in the handling of certificate validation in curl v8.1.0, particularly in how wildcard patterns are matched when listed as “Subject Alternative Name” in TLS server certificates. Curls can be modified to use its own name matching function for TLS, rather than the one...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: tls: Always refresh the queue when reading sock. After recent changes in net-next, TCP compacts skb much more aggressively. This uncovered a bug in TLS, where we might attempt to operate on an old skb when checking whether all sk...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net/tls: The issue of “use-after-free” after the TLS device goes down and up has been fixed. When a netdev with active TLS offloading goes down, the tlsdevicedown function is called to stop the offloading and tear down the TLS...
