Description

This security bulletin contains information about 9 vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2026-43909)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code or cause a denial of service.

The vulnerability exists due to integer overflow in SwapRGBABytes() in the DPX ABGR decoder when parsing a crafted kABGR DPX image with large dimensions. A remote attacker can supply a specially crafted DPX file to execute arbitrary code or cause a denial of service.

User interaction is required to open or process the crafted DPX file.


2) Integer overflow (CVE-ID: CVE-2026-43908)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to cause a denial of service and potentially execute arbitrary code.

The vulnerability exists due to integer overflow leading to an out-of-bounds write in the ConvertCbYCrYToRGB function in the DPX 4:2:2 decoder when parsing a crafted DPX file. A remote attacker can supply a specially crafted DPX file to cause a denial of service and potentially execute arbitrary code.

User interaction is required to open or process a crafted DPX file.


3) Integer overflow (CVE-ID: CVE-2026-43907)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to cause a denial of service and overwrite heap memory.

The vulnerability exists due to integer overflow in QueryRGBBufferSizeInternal in the DPX decoder when parsing a crafted DPX file with kCbYCr or kABGR descriptors. A remote attacker can supply a specially crafted DPX file to cause a denial of service and overwrite heap memory.

User interaction is required to open or process the crafted DPX file through a code path that reads pixel data.


4) Out-of-bounds read (CVE-ID: CVE-2026-43996)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to out-of-bounds read in TGAInput::decode_pixel in the TGA paletted image decoder when parsing a crafted TYPE_PALETTED TGA file with 32-bit palette entries. A remote attacker can trick the victim into opening a crafted file to cause a denial of service.

User interaction is required to open a crafted file.


5) Heap-based buffer overflow (CVE-ID: CVE-2026-43906)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to a heap-based buffer overflow in the HEIF decoder when processing crafted HEIF images with mismatched subimage metadata. A remote attacker can supply a specially crafted image to execute arbitrary code.

The issue occurs when a larger scanline from one subimage is copied into a buffer allocated for a smaller subimage after subimage switching.


6) Integer overflow (CVE-ID: CVE-2026-43905)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to integer overflow or wraparound in the JPEG2000 reader buffer allocation in jpeg2000input.cpp when parsing a crafted JPEG2000 file with large dimensions. A remote attacker can supply a specially crafted JPEG2000 file to execute arbitrary code.

Only builds compiled with the USE_OPENJPH flag are vulnerable. User interaction is required to open the crafted file.


7) Out-of-bounds write (CVE-ID: CVE-2026-43904)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to out-of-bounds write in the Softimage PIC RLE decoder when parsing a crafted .pic file. A remote attacker can trick the victim into opening a crafted file to execute arbitrary code.

User interaction is required to open a crafted file.


8) Out-of-bounds write (CVE-ID: CVE-2026-43903)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to out-of-bounds write in the SGI RLE decoder when parsing a crafted .sgi file. A remote attacker can supply a crafted .sgi file with an RLE count exceeding the scanline width to cause a denial of service.

User interaction is required to open the crafted file, and the issue affects release builds where the bounds checks compile to no-ops.


9) Out-of-bounds write (CVE-ID: CVE-2026-7582)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to out-of-bounds write in the DDS image decoder when parsing a crafted DDS file. A remote attacker can supply a specially crafted DDS file to execute arbitrary code.

The issue is caused by a signed 32-bit integer overflow in ddsinput.cpp before widening to size_t, which can lead to writes beyond the allocated image buffer.
