CVSS v3.1 |
| pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions prior to 6.10.1 can craft a PDF which leads to long runtimes. This requires cross-reference streams with wrong large `/Size` values or object streams with wrong large `/N` values. This has been fixed in pypdf 6.10.1. As a workaround, one may apply the changes from the patch manually. |
| The leancrypto library is a cryptographic library that exclusively contains only PQC-resistant cryptographic algorithms. Prior to version 1.7.1, lc_x509_extract_name_segment() casts size_t vlen to uint8_t when storing the Common Name (CN) length. An attacker who crafts a certificate with CN = victim's CN + 256 bytes padding gets cn_size = (uint8_t)(256 + N) = N, where N is the victim's CN length. The first N bytes of the attacker's CN are the victim's identity. After parsing, the attacker's certificate has an identical CN to the victim's — enabling identity impersonation in PKCS#7 verification, certificate chain matching, and code signing. This issue has been patched in version 1.7.1. |
| libsixel 1.8.1 has a memory leak in sixel_decoder_decode in decoder.c, image_buffer_resize in fromsixel.c, and sixel_decode_raw in fromsixel.c. |
| libsixel 1.8.1 has a memory leak in sixel_allocator_new in allocator.c. |
| There is a heap-based buffer over-read at stb_image_write.h (function: stbi_write_png_to_mem) in libsixel 1.8.2 that will cause a denial of service. |
| There is an illegal address access at fromsixel.c (function: sixel_decode_raw_impl) in libsixel 1.8.2 that will cause a denial of service. |
| There is a heap-based buffer overflow at fromsixel.c (function: image_buffer_resize) in libsixel 1.8.2 that will cause a denial of service or possibly unspecified other impact. |
| There is a heap-based buffer over-read at writer.c (function: write_png_to_file) in libsixel 1.8.2 that will cause a denial of service. |
| An issue was discovered in libsixel 1.8.2. There is an integer overflow in the function sixel_encode_body at tosixel.c. |
| An issue was discovered in libsixel 1.8.2. There is an integer overflow in the function sixel_decode_raw_impl at fromsixel.c. |
| An issue was discovered in libsixel 1.8.2. There is a heap-based buffer overflow in the function load_pnm at frompnm.c, due to an integer overflow. |
| An issue was discovered in libsixel 1.8.2. There is a heap-based buffer over-read in the function load_sixel at loader.c. |
| A memory leak was discovered in image_buffer_resize in fromsixel.c in libsixel 1.8.4. |
| A heap-based buffer overflow was discovered in image_buffer_resize in fromsixel.c in libsixel before 1.8.4. |
| In libsixel v1.8.2, there is an infinite loop in the function sixel_decode_raw_impl() in the file fromsixel.c, as demonstrated by sixel2png. |
| In libsixel v1.8.2, there is a heap-based buffer over-read in the function load_jpeg() in the file loader.c, as demonstrated by img2sixel. |
| Libsixel 1.8.3 contains a heap-based buffer overflow in the sixel_encode_highcolor function in tosixel.c. |
| libsixel 1.8.6 suffers from a Heap Use After Free vulnerability in in libsixel/src/dither.c:388. |
| There is a floating point exception error in sixel_encoder_do_resize, encoder.c:633 in libsixel img2sixel 1.8.6. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted JPEG file. |
| There is a heap-based buffer over-read at stb_image.h (function: stbi__tga_load) in libsixel 1.8.2 that will cause a denial of service. |
