FAQs regarding Amazon Linux ALAS/CVE Severity

Issue Overview:

In GNOME GdkPixbuf (aka gdk-pixbuf) through 2.42.10, the ANI (Windows animated cursor) decoder encounters heap memory corruption (in ani_load_chunk in io-ani.c) when parsing chunks in a crafted .ani file. A crafted file could allow an attacker to overwrite heap metadata, leading to a denial of service or code execution attack. This occurs in gdk_pixbuf_set_option() in gdk-pixbuf.c. (CVE-2022-48622)

A flaw was found in the GIF parser of GdkPixbuf's LZW decoder. When an invalid symbol is encountered during decompression, the decoder sets the reported output size to the full buffer length rather than the actual number of written bytes. This logic error results in uninitialized sections of the buffer being included in the output, potentially leaking arbitrary memory contents in the processed image. (CVE-2025-6199)

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 causing application crashes or arbitrary code execution. (CVE-2025-7345)

Issue Correction:
Run dnf update gdk-pixbuf2 --releasever 2023.8.20250808 or dnf update --advisory ALAS2023-2025-1120 --releasever 2023.8.20250808 to update your system.
