Affected: AlmaLinux:9: gnutls, AlmaLinux:9: gnutls-c++, AlmaLinux:9: gnutls-dane, AlmaLinux:9: gnutls-devel, AlmaLinux:9: gnutls-utils

The gnutls packages provide the GNU Transport Layer Security (GnuTLS) library, which implements cryptographic algorithms and protocols such as SSL, TLS, and DTLS.

Nettle is a cryptographic library that is designed to fit easily in almost any context: In crypto toolkits for object-oriented languages, such as C++, Python, or Pike, in applications like LSH or GNUPG, or even in kernel space.

The following packages have been upgraded to a later upstream version: gnutls (3.7.6), nettle (3.8).

Security Fix(es):

* gnutls: Double free during gnutls_pkcs7_verify. (CVE-2022-2509)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* [IBM 9.1] [P10] POWER10 performance enhancements for cryptography: nettle - incremental work (BZ#2102589) * Allow enabling KTLS in AlmaLinux 9.1 (BZ#2108532) * DES-CBC bag is decryptable under FIPS (BZ#2115314) * allow signature verification using RSA keys <2k in FIPS mode (BZ#2119770)

expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees run-mailcap in the Debian mime-support package before 3.52-1+deb7u1 allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a filename. In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start o…

GnuTLS is a secure communications library implementing the SSL, TLS and DTLS protocols and technologies around them. It provides a simple C language application programming interface (API) to access the secure communications protocols as well as APIs to parse and write X.509, PKCS #12, and other required structures.The project strives to provide a secure communications back-end, simple to use and integrated with the rest of the base Linux libraries. A back-end designed to work and be secure out of the box, keeping the complexity of TLS and PKI out of application code. Security Fix(es): A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function.(CVE-2022-2509)

A new LTS Firmware release fixes known vulnerabilities in used open-source libraries. In addition, the following improvements have been implemented: HMI - Hardening against DoS attacks. - Hardening against memory leak problems in case of network attacks. WBM - Umlauts in the password of the 'User Manager' were not handled correctly. The password rule for upper and lower case was not followed. This could lead to unintentionally weaker passwords.- Hardening of WBM against Cross-Site-Scripting. User Manager - In security notifications 'SecurityToken' was always displayed as '0000000' when creating or modifying users.- Hardening of Trust and Identity Stores.
