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-2025-6199 [LOW] GDK-PixBuf vulnerabilities
Title: GDK-PixBuf vulnerabilities
Summary: Several security issues were fixed in GDK-PixBuf.
It was discovered that GDK-Pixbuf incorrectly handled certain
GIF files. An attacker could possibly use this issue to expose
sensitive information. This issue only affected Ubuntu 25.04,
Ubuntu 24.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 20.04 LTS.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

CVE-2025-7345 [HIGH] CWE-120 gdk‑pixbuf: Heap‑buffer‑overflow in gdk‑pixbuf
gdk‑pixbuf: Heap‑buffer‑overflow in gdk‑pixbuf
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.
