CVE-2026-111125debiancfitsio+3
EPSS score0.13%
CFITSIO through 4.7.0 contains a heap-based out-of-bounds read vulnerability in the HCOMPRESS tile decoder that allows attackers to read past the compressed tile buffer via input_nnybble in fits_hdecompress.c. Attackers can supply a crafted FITS file with ZCMPTYPE HCOMPRESS_1 declaring oversized tile geometry to crash applications calling fits_read_pix or disclose limited heap memory.CVE-2026-111124debiancfitsio+3EPSS score0.13%
CFITSIO through 4.7.0 contains a heap-based out-of-bounds read vulnerability in the imcompress.c unquantize helpers that allows attackers to read memory before the fits_rand_value table via a zero or negative ZDITHER0 seed. Attackers can supply a crafted FITS file with a SUBTRACTIVE_DITHER_1 compressed image, read through fits_open_file() and fits_read_pix(), to cause crashes or leak heap contents in decoded pixels.CVE-2018-3846debiancfitsio+4EPSS score3.02%
In the ffgphd and ffgtkn functions in NASA CFITSIO 3.42, specially crafted images parsed via the library can cause a stack-based buffer overflow overwriting arbitrary data. An attacker can deliver an FIT image to trigger this vulnerability and potentially gain code execution.CVE-2018-3848debiancfitsio+4EPSS score3.50%
In the ffghbn function in NASA CFITSIO 3.42, specially crafted images parsed via the library can cause a stack-based buffer overflow overwriting arbitrary data. An attacker can deliver an FIT image to trigger this vulnerability and potentially gain code execution.CVE-2018-3847debiancfitsio+2EPSS score2.84%
Multiple exploitable buffer overflow vulnerabilities exist in image parsing functionality of the CFITSIO library version 3.42. Specially crafted images parsed via the library, can cause a stack-based buffer overflow overwriting arbitrary data. An attacker can deliver an FIT image to trigger this vulnerability and potentially gain code execution.CVE-2018-3849debiancfitsio+4EPSS score3.64%
In the ffghtb function in NASA CFITSIO 3.42, specially crafted images parsed via the library can cause a stack-based buffer overflow overwriting arbitrary data. An attacker can deliver an FIT image to trigger this vulnerability and potentially gain code execution.CVE-2019-1010060debiancfitsio+2EPSS score7.17%
NASA CFITSIO prior to 3.43 is affected by: Buffer Overflow. The impact is: arbitrary code execution. The component is: over 40 source code files were changed. The attack vector is: remote unauthenticated attacker. The fixed version is: 3.43. NOTE: this CVE refers to the issues not covered by CVE-2018-3846, CVE-2018-3847, CVE-2018-3848, and CVE-2018-3849. One example is ftp_status in drvrnet.c mishandling a long string beginning with a '4' character.
