CVE-2026-18090— Gdk-pixbuf: gdk-pixbuf: heap out-of-bounds read in uncompress() via crafted icns rle block
Quick assessment
Affected
Red Hat Red Hat Enterprise Linux 10
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
GNOME gdk-pixbuf是GNOME基金会开源的一款图像加载与处理库。 GNOME gdk-pixbuf存在缓冲区错误漏洞，该漏洞源于uncompress()函数处理RLE编码的ICNS图标数据时未验证源缓冲区边界，导致堆越界读取，可能允许远程攻击者通过提供特制的Apple Icon Image文件造成拒绝服务（应用程序崩溃）或信息泄露，泄露相邻内存中的敏感数据。

Vulnerability Title
Gdk-pixbuf: gdk-pixbuf: heap out-of-bounds read in uncompress() via crafted icns rle block
Source: CVE Program / CVE List V5
Vulnerability Description
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 can lead to a denial of service, where the application crashes, or to information disclosure, potentially revealing sensitive data from adjacent memory.
