Affected: Alpaquita:23: gdk-pixbuf, Alpaquita:25: gdk-pixbuf, Alpaquita:stream: 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.

gdk is written in C but has been designed from the ground up to support a wide range of languages. It provide a complete set of widgets,and suitable for projects ranging from small one-off tools to complete application suites. Security Fix(es):

A vulnerability was found in gdk‑pixbuf (affected version not known). It has been rated as critical.Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().Impacted is confidentiality, integrity, and availability.There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.(CVE-2025-7345)
