An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to pattern match, but the wildcard check in curl could still check for `x*`, which would match even though the IDN name most likely contained nothing even resembling an `x`.

A new security flaw has been disclosed in the Google Cloud Platform's (GCP) Cloud SQL service that could be potentially exploited to obtain access to confidential data. "The vulnerability could have enabled a malicious actor to escalate from a basic Cloud SQL user to a full-fledged sysadmin on a container, gaining access to internal GCP data like secrets, sensitive files, passwords, in addition

Ubuntu Security Notice 6109-1 - Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service. Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information.

A heap-based buffer overflow issue was discovered in libjpeg-turbo in h2v2_merged_upsample_internal() function of jdmrgext.c file. The vulnerability can only be exploited with 12-bit data precision for which the range of the sample data type exceeds the valid sample range, hence, an attacker could craft a 12-bit lossless JPEG image that contains out-of-range 12-bit samples. An application attempting to decompress such image using merged upsampling would lead to segmentation fault or buffer overflows, causing an application to crash.
