Debian Linux Security Advisory 5611-1 - The Qualys Research Labs discovered several vulnerabilities in the GNU C Library's __vsyslog_internal() function (called by syslog() and vsyslog()). A heap-based buffer overflow (CVE-2023-6246), an off-by-one heap overflow (CVE-2023-6779) and an integer overflow (CVE-2023-6780) can be exploited for privilege escalation or denial of service.

Gentoo Linux Security Advisory 202401-32 - Multiple vulnerabilities have been discovered in libaom, the worst of which can lead to remote code execution. Versions greater than or equal to 3.2.0 are affected.

Gentoo Linux Security Advisory 202401-31 - Multiple vulnerabilities have been found in containerd, the worst of which could result in privilege escalation. Versions greater than or equal to 1.6.14 are affected.

Gentoo Linux Security Advisory 202401-30 - Multiple vulnerabilities have been discovered in the Xorg Server and XWayland, the worst of which can result in privilege escalation or remote code execution. Versions greater than or equal to 21.1.11 are affected.

Ubuntu Security Notice 6609-2 - Lin Ma discovered that the netfilter subsystem in the Linux kernel did not properly validate network family support while creating a new netfilter table. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information.

A vulnerability exists within Mirth Connect due to its mishandling of deserialized data. This vulnerability can be leveraged by an attacker using a crafted HTTP request to execute OS commands within the context of the target application. The original vulnerability was identified by IHTeam and assigned CVE-2023-37679. Later, researchers from Horizon3.ai determined the patch to be incomplete and published a gadget chain which bypassed the deny list that the original had implemented. This second vulnerability was assigned CVE-2023-43208 and was patched in Mirth Connect version 4.4.1. This Metasploit module has been tested on versions 4.1.1, 4.3.0 and 4.4.0.

Ubuntu Security Notice 6587-3 - USN-6587-1 fixed vulnerabilities in X.Org X Server. The fix was incomplete resulting in a possible regression. This update fixes the problem. Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled memory when processing the DeviceFocusEvent and ProcXIQueryPointer APIs. An attacker could possibly use this issue to cause the X Server to crash, obtain sensitive information, or execute arbitrary code. Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled reattaching to a different master device. An attacker could use this issue to cause the X Server to crash, leading to a denial of service, or possibly execute arbitrary code. Olivier Fourdan and Donn Seeley discovered that the X.Org X Server incorrectly labeled GLX PBuffers when used with SELinux. An attacker could use this issue to cause the X Server to crash, leading to a denial of service. Olivier Fourdan discovered that the X.Org X Server incorrectly handled the curser co...

Malicious local attackers can obtain full root access on Linux machines by taking advantage of a newly disclosed security flaw in the GNU C library (aka glibc). Tracked as CVE-2023-6246, the heap-based buffer overflow vulnerability is rooted in glibc's __vsyslog_internal() function, which is used by syslog() and vsyslog() for system logging purposes. It's said to have been accidentally

### Summary Hello 👋 `goreleaser release --debug` log shows secret values used in the in the custom publisher. How to reproduce the issue: - Define a custom publisher as the one below. Make sure to provide a custom script to the `cmd` field and to provide a secret to `env` ``` #.goreleaser.yml publishers: - name: my-publisher # IDs of the artifacts we want to sign ids: - linux_archives - linux_package cmd: "./build/package/linux_notarize.sh" env: - VERSION={{ .Version }} - SECRET_1={{.Env.SECRET_1}} - SECRET_2={{.Env.SECRET_2}} ``` - run `goreleaser release --debug` You should see your secret value in the gorelease log. The log shows also the `GITHUB_TOKEN` Example: ``` running cmd= .... SECRET_1=secret_value ```
