Mageia 2023-0131: tigervnc/x11-server security update

A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later. (CVE-2023-1393)

Mageia 2023-0130: openssl security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted

Mageia 2023-0126: python-cairosvg security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

CairoSVG is an SVG converter based on Cairo, a 2D graphics library. Prior to version 2.7.0, Cairo can send requests to external hosts when processing SVG files. A malicious actor could send a specially crafted SVG file that allows them to perform a server-side request forgery or denial of service. Version 2.7.0 disables CairoSVG's ability to access other

Mageia 2023-0122: dino security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

When a Dino client receives a specifically crafted message from an unauthorized sender, it would use information from that message to add, update or remove entries in the user’s personal bookmark store without requiring further user interaction. (CVE-2023-28686)

Mageia 2023-0117: snort security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured File Policy for HTTP. The vulnerability is due to incorrect detection of modified HTTP packets used in chunked responses. An attacker could exploit this vulnerability by sending crafted HTTP packets

Mageia 2023-0116: thunderbird security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Incorrect code generation during JIT compilation. (CVE-2023-25751) Potential out-of-bounds when accessing throttled streams. (CVE-20223-25752) Invalid downcast in Worklets. (CVE-2023-28162) URL being dragged from a removed cross-origin iframe into the same tab triggered navigation. (CVE-2023-28164)

Mageia 2023-0115: flatpak security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

If a malicious Flatpak app is run on a Linux virtual console such as /dev/tty1, it can copy text from the virtual console and paste it back into the virtual console's input buffer, from which the command might be run by the user's shell after the Flatpak app has exited. This is similar to CVE-2017-5226, but using the TIOCLINUX ioctl command instead

Mageia 2023-0112: python-owslib security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E
