RedHat on Friday released an "urgent security alert" warning that two versions of a popular data compression library called XZ Utils (previously LZMA Utils) have been backdoored with malicious code designed to allow unauthorized remote access. The software supply chain compromise, tracked as CVE-2024-3094, has a CVSS score of 10.0, indicating maximum severity. It impacts XZ Utils

This Metasploit module exploits a buffer overflow at the administration interface (8080 or 4117) of WatchGuard Firebox and XTM appliances which is built from a cherrypy python backend sending XML-RPC requests to a C binary called wgagent using pre-authentication endpoint /agent/login. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2. Successful exploitation results in remote code execution as user nobody.

Debian Linux Security Advisory 5649-1 - Andres Freund discovered that the upstream source tarballs for xz-utils, the XZ-format compression utilities, are compromised and inject malicious code, at build time, into the resulting liblzma5 library.

Debian Linux Security Advisory 5648-1 - Security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure.

Ubuntu Security Notice 6707-4 - Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle element deactivation in certain cases, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6704-4 - It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service. Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly handle session setup requests. A remote attacker could possibly use this to cause a denial of service.

Details have emerged about a vulnerability impacting the "wall" command of the util-linux package that could be potentially exploited by a bad actor to leak a user's password or alter the clipboard on certain Linux distributions. The bug, tracked as CVE-2024-28085, has been codenamed WallEscape by security researcher Skyler Ferrante. It has been described as a case of improper

Updated March 30, 2024: We have determined that Fedora Linux 40 beta does contain two affected versions of xz libraries - xz-libs-5.6.0-1.fc40.x86_64.rpm and xz-libs-5.6.0-2.fc40.x86_64.rpm. At this time, Fedora 40 Linux does not appear to be affected by the actual malware exploit, but we encourage all Fedora 40 Linux beta users to revert to 5.4.x versions.Editor's note: This post has been updated to more clearly articulate the affected versions of Fedora Linux and add additional mitigation methods.Yesterday, Red Hat Information Risk and Security and Red Hat Product Security learned that the l

### Impact _What kind of vulnerability is it? Who is impacted?_ Users running containers with root privileges allowing a container to run with read/write access to the host system files when selinux is not enabled. With selinux enabled, some read access is allowed. ### Patches From @nalind . This is a patch for Buildah (https://github.com/containers/buildah). Once fixed there, Buildah will be vendored into Podman. ``` # cat /root/cve-2024-1753.diff --- internal/volumes/volumes.go +++ internal/volumes/volumes.go @@ -11,6 +11,7 @@ import ( "errors" + "github.com/containers/buildah/copier" "github.com/containers/buildah/define" "github.com/containers/buildah/internal" internalParse "github.com/containers/buildah/internal/parse" @@ -189,7 +190,11 @@ func GetBindMount(ctx *types.SystemContext, args []string, contextDir string, st // buildkit parity: support absolute path for sources from current build context if contextDir != "" { // path should be /contextDir/speci...
