libexpat in Expat before 2.7.2 allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing.

802.1X. An authentication issue was addressed with improved state management.

When a highly-privileged, authenticated attacker attempts to initialize the rSeries FIPS module using a password with special shell metacharacters, arbitrary system commands may be executed, and the FIPS hardware security module (HSM) may fail to initialize. A successful exploit can allow the attacker to cross a security boundary.

An out-of-bounds write vulnerability exists in F5OS-A and F5OS-C that could lead to memory corruption.

A use-after-free vulnerability was found in libxslt while parsing xsl nodes that may lead to the dereference of expired pointers and application crash.

HTTP response splitting in the core of Apache HTTP Server allows an attacker who can manipulate the Content-Type response headers of applications hosted or proxied by the server can split the HTTP response. This vulnerability was described as CVE-2023-38709 but the patch included in Apache HTTP Server 2.4.59 did not address the issue. Users are recommended to upgrade to version 2.4.64, which fixes this issue.

CVE-2024-39279 Insufficient granularity of access control in UEFI firmware in some Intel(R) processors may allow a authenticated user to potentially enable denial of service via local access. CVE-2024-28047 Improper input validation in UEFI firmware for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

CVE-2024-28047 Improper input validation in UEFI firmware for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

A certificate with a URI which has a IPv6 address with a zone ID may incorrectly satisfy a URI name constraint that applies to the certificate chain.

Certificates containing URIs are not permitted in the web PKI, so this only affects users of private PKIs which make use of URIs.

Improper conditions check in some Intel(R) Processors with Intel(R) SGX may allow a privileged user to potentially enable information disclosure via local access.

CPython 3.9 and earlier doesn't disallow configuring an empty list ("[]") for SSLContext.setnpnprotocols() which is an invalid value for the underlying OpenSSL API. This results in a buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically a protocol name would be configured).

drivers/usb/mon/monbin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-space client to corrupt the monitor's internal memory.

In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c.

HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are recommended to upgrade to version 2.4.59, which fixes this issue.

Accounts. The issue was addressed with improved checks.

A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative executable code paths.

In the Linux kernel, the following vulnerability has been resolved:

sched/membarrier: reduce the ability to hammer on sysmembarrier

On some systems, sysmembarrier can be very expensive, causing overall slowdowns for everything. So put a lock on the path in order to serialize the accesses to prevent the ability for this to be called at too high of a frequency and saturate the machine.

CVE-2023-5981 A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. CVE-2024-0553 A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.

A fundamental design flaw within the RADIUS protocol has been proven to be exploitable, compromising the integrity in the RADIUS Access-Request process. The attack allows a malicious user to modify packets in a way that would be indistinguishable to a RADIUS client or server. To be successful, the attacker must have the ability to inject themselves between the client and server.

Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow. Impact summary: Applications that use the functions DHgeneratekey() to generate an X9.42 DH key may experience long delays. Likewise, applications that use DHcheckpubkey(), DHcheckpubkeyex() or EVPPKEYpubliccheck() to check an X9.42 DH key or X9.42 DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. While DHcheck() performs all the necessary checks (as of CVE-2023-3817), DHcheckpubkey() doesn't make any of these checks, and is therefore vulnerable for excessively large P and Q parameters. Likewise, while DHgeneratekey() performs a check for an excessively large P, it doesn't check for an excessively large Q. An application that calls DHgeneratekey() or DHcheckpubkey() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a Denial of Service attack. DHgeneratekey() and DHcheckpubkey() are also called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DHcheckpubkeyex(), EVPPKEYpubliccheck(), and EVPPKEYgenerate(). Also vulnerable are the OpenSSL pkey command line application when using the "-pubcheck" option, as well as the OpenSSL genpkey command line application. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.

An issue was discovered in function libssh2packetadd in libssh2 1.10.0 allows attackers to access out of bounds memory.

Accessibility. A privacy issue was addressed with improved private data redaction for log entries.

A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.

Excessive time spent in DH check / generation with large Q parameter value

It was discovered that the numerical library used in NSS for RSA cryptography leaks information whether high order bits of the RSA decryption result are zero. This information can be used to mount a Bleichenbacher or Manger like attack against all RSA decryption operations. As the leak happens before any padding operations, it affects all padding modes: PKCS#1 v1.5, OAEP, and RSASVP. Both API level calls and TLS server operation are affected.
