Vulnerabilidades

A flaw was found in gdk-pixbuf. This vulnerability allows a remote attacker to cause a heap out-of-bounds read by providing a specially crafted Apple Icon Image (.icns) file. The uncompress() function, which handles RLE-encoded ICNS icon data, fails to validate the source buffer's boundaries during decompression. This…

A flaw was found in gdk-pixbuf. When loading a specially crafted JPEG image containing chunked ICC profile markers, an error during ICC profile parsing can leave stale size metadata after the profile buffer is freed. A subsequent allocation in the same decode can cause an out-of-bounds write, potentially crashing the…

A flaw was found in gdk-pixbuf. When parsing a specially crafted ICO file with pixel values that exceed the defined palette range, an out-of-bounds read can occur due to improper bounds checking against the actual palette size. This vulnerability causes heap bytes to be interpreted as valid palette indices and…

A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail…

A flaw exists in gdk‑pixbuf within the gdk_pixbuf__jpeg_image_load_increment function (io-jpeg.c) and in glib’s g_base64_encode_step (glib/gbase64.c). When processing maliciously crafted JPEG images, a heap buffer overflow can occur during Base64 encoding, allowing out-of-bounds reads from heap memory, potentially…

GNOME GdkPixbuf (aka GDK-PixBuf) before 2.42.8 allows a heap-based buffer overflow when compositing or clearing frames in GIF files, as demonstrated by io-gif-animation.c composite_frame. This overflow is controllable and could be abused for code execution, especially on 32-bit systems.

A flaw was found in gdk-pixbuf in versions before 2.42.0. An integer wraparound leading to an out of bounds write can occur when a crafted GIF image is loaded. An attacker may cause applications to crash or could potentially execute code on the victim system. The highest threat from this vulnerability is to data…

GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. if c->self_code equals 10, self->code_table[10].extends will assign the value 11 to c. The next execution in the loop will assign self->code_table[11].extends to c, which will give the…

gdk-pixbuf through 2.31.1 has GIF loader buffer overflow when initializing decompression tables due to an input validation flaw

GdkPixBuf (aka gdk-pixbuf), possibly 2.32.2, as used by GNOME Nautilus 3.14.3 on Ubuntu 16.04, allows attackers to cause a denial of service (stack corruption) or possibly have unspecified other impact via a crafted file folder.

Gnome gdk-pixbuf 2.36.8 and older is vulnerable to several integer overflow in the gif_get_lzw function resulting in memory corruption and potential code execution

An exploitable integer overflow vulnerability exists in the tiff_image_parse functionality of Gdk-Pixbuf 2.36.6 when compiled with Clang. A specially crafted tiff file can cause a heap-overflow resulting in remote code execution. An attacker can send a file or a URL to trigger this vulnerability.

An exploitable heap overflow vulnerability exists in the gdk_pixbuf__jpeg_image_load_increment functionality of Gdk-Pixbuf 2.36.6. A specially crafted jpeg file can cause a heap overflow resulting in remote code execution. An attacker can send a file or url to trigger this vulnerability.

The make_available_at_least function in io-tiff.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (infinite loop) via a large TIFF file.

Integer underflow in the load_resources function in io-icns.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (out-of-bounds read and program crash) via a crafted image entry size in an ICO file.

Integer overflow in io-ico.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (segmentation fault and application crash) via a crafted image entry offset in an ICO file, which triggers an out-of-bounds read, related to compiler optimizations.

gdk-pixbuf-thumbnailer.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors related to printing an error message.

The OneLine32 function in io-ico.c in gdk-pixbuf before 2.35.3 allows remote attackers to cause a denial of service (out-of-bounds write and crash) via crafted dimensions in an ICO file.

Multiple integer overflows in the (1) pixops_composite_nearest, (2) pixops_composite_color_nearest, and (3) pixops_process functions in pixops/pixops.c in gdk-pixbuf before 2.33.1 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted image, which…

Integer overflow in the pixops_scale_nearest function in pixops/pixops.c in gdk-pixbuf before 2.32.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted GIF image file, which triggers a heap-based buffer overflow.

io-tga.c in gdk-pixbuf before 2.32.0 uses heap memory after its allocation failed, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) and possibly execute arbitrary code via a crafted Truevision TGA (TARGA) file.

Integer overflow in the make_filter_table function in pixops/pixops.c in gdk-pixbuf before 2.31.5, as used in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 on Linux, Google Chrome on Linux, and other products, allows remote attackers to execute arbitrary code or cause a denial of service (heap-based…

Multiple integer overflows in the read_bitmap_file_data function in io-xbm.c in gdk-pixbuf before 2.26.1 allow remote attackers to cause a denial of service (application crash) via a negative (1) height or (2) width in an XBM file, which triggers a heap-based buffer overflow.

The gdk_pixbuf__gif_image_load function in gdk-pixbuf/io-gif.c in gdk-pixbuf before 2.23.5 does not properly handle certain return values, which allows remote attackers to cause a denial of service (memory consumption) via a crafted GIF image file.
