gstreamer1-plugins-bad-free: GStreamer: Heap buffer overflow via crafted VNC server rectangle in librfb

A heap buffer overflow vulnerability was found in GStreamer's librfb RFB/VNC client. The rectangle bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: fbdev: Added bounds checking in bitputcs to prevent out-of-bounds writes using vmalloc. Added bounds checking to prevent writes beyond the framebuffer boundaries when rendering text near the screen edges. Return early if the Y...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fbdev: bitblit: In the bitPutcs function, the bound-check glyph index was derived from the character value masked by 0xff or 0x1ff. This may lead to reading beyond the end of the built-in font array, exceeding the actual number o...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fbdev: In of: displaytiming, there is a fix for the refcount leak in ofgetdisplaytimings. The function ofparsephandle returns a devicenode with the refcount incremented. This value is stored in ‘entry’ and then copied to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fbcon: Set fbdisplayi-mode to NULL when the mode is released. Recently, we discovered the following issue through syzkaller: BUG: KASAN: Slab-use-after-free in fbmodeisequal+0x285/0x2f0 A read of size 4 at address ff11000001b3c69...

The vulnerability of the imxfb_probe() function in the drivers/video/fbdev/imxfb.c file of the Linux kernel-based graphics buffer device driver allows a hacker to cause a service failure.

The vulnerability of the imxfbprobe function in the drivers/video/fbdev/imxfb.c file of the Linux kernel-based device driver for frame buffer devices is related to the reallocation of previously released memory. Exploiting this vulnerability could allow an attacker to cause a system failure...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the rfbsrc process when connecting to a malicious RFB/VNC server that advertises a 16bpp framebuffer and sends Hextile-encoded updates. An attacker can cause a process crash or potentially corrupt memory by...

kernel: drm/gem: Fix inconsistent plane dimension calculation in drm_gem_fb_init_with_funcs()

A flaw was found in the Linux kernel's Direct Rendering Manager DRM Graphics Execution Manager GEM component. This vulnerability arises from an inconsistent calculation of plane dimensions, which can lead to incorrect memory allocation checks. A local attacker could exploit this by creating a...

GHSA-66M8-C62J-H6V5 jxl-oxide: `FrameBuffer::new` creates out-of-bounds slices on overflow

Summary jxl-oxide exposes a public safe API that can construct an undersized FrameBuffer due to unchecked usize multiplication, which immediately trigger panic while initializing the buffer in normal decoding path. Additionally, calling the safe grouped buffer accessors afterward can create inval...
