SUSE CVE-2026-54060

Pillow is a Python imaging library. Prior to 12.3.0, PIL/FontFile.py FontFile.compile assembled per-glyph images into a combined bitmap with Image.new"1", xsize, ysize without calling Image.decompressionbombcheck, allowing a font to trigger excessive allocation during conversion or saving. This...

freerdp: FreeRDP: Out-of-bounds write in planar bitmap decoder allows arbitrary code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The planar bitmap decoder contains an out-of-bounds heap write vulnerability when processing RLE planar data. A remote attacker could exploit this by providing specially crafted RLE planar data, leading to an...

CVE-2026-55379

Pillow is a Python imaging library. Prior to 12.3.0, PIL/BdfFontFile.py bdfchar read the BBX width and height field from a BDF font file and passed attacker-controlled dimensions to Image.new without calling Image.decompressionbombcheck, bypassing Pillow's documented decompression bomb protection...

CVE-2026-54060

The issue affects Pillow (Python imaging library). In FontFile.compile(), per-glyph images were assembled into a single bitmap using Image.new("1", (xsize, ysize)) without calling Image._decompression_bomb_check(), enabling an attacker to trigger excessive memory allocation during conversion or s...

Improper Restriction of Operations within the Bounds of a Memory Buffer in OpenCV

OpenCV Open Source Computer Vision Library through 3.3 corresponding to OpenCV-Python 3.3.0.9 has a buffer overflow in the cv::BmpDecoder::readData function in modules/imgcodecs/src/grfmtbmp.cpp when reading an image file by using cv::imread, as demonstrated by the 4-buf-overflow-readData-memcpy...

dnsmasq: NSEC bitmap parsing infinite loop

A denial of service vulnerability was discovered in dnsmasq's DNSSEC validation. When parsing NSEC and NSEC3 bitmap records, the window iteration logic fails to account for the 2-byte window header when advancing through the bitmap data. A specially crafted DNS response with a zero-length bitmap...
