GIMP ICNS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of ICNS files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28530.

    Several vulnerabilities were discovered in GIMP, the GNU Image     Manipulation Program, which could result in denial of service or     potentially the execution of arbitrary code if malformed XWD, ICNS, PGM     or ICO files are opened.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 2.10.34-1+deb12u9.

    For the stable distribution (trixie), these problems have been fixed in     version 3.0.4-3+deb13u7.

    We recommend that you upgrade your gimp packages.

    For the detailed security status of gimp please refer to     its security tracker page at:
