gvfs: SFTP: heap-based buffer overflow in read_reply()

A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause readreply to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing...

gimp: GIMP: Remote code execution via TIF file parsing heap-based buffer overflow

A flaw was found in GIMP. This heap-based buffer overflow vulnerability in the TIF file parsing component allows remote attackers to execute arbitrary code. Successful exploitation requires user interaction, where a target must open a malicious TIF file. An attacker can leverage this to execute...

gimp: integer overflow in file-fits plugin causes a heap-based buffer overflow on crafted FITS images

A flaw was found in the file-fits plugin in GIMP. When processing a FITS image file, the plugin calculates memory allocation sizes using signed 32-bit integers for width and height. If a crafted file sets both values to large values, their product exceeds 2^31 and overflows, resulting in an...

gimp: GIMP: Remote code execution via TIF file parsing heap-based buffer overflow

A flaw was found in GIMP. This heap-based buffer overflow vulnerability in the TIF file parsing component allows a remote attacker to execute arbitrary code. User interaction is required, as the target must open a specially crafted malicious TIF file. Successful exploitation can lead to arbitrary...
