CVE-2026-68767 (GCVE-0-2026-68767)

Vulnerability from cvelistv5 – Published: 2026-08-22 14:12 – Updated: 2026-08-26 16:16

Title

hashcat through 7.1.2 Off-by-One Out-of-Bounds Heap Write in fgetl()

Summary

hashcat's fgetl() function in src/filehandling.c writes a null terminator one byte past the caller's buffer when an input line is exactly the buffer length. Attackers can trigger this out-of-bounds heap write by providing a hash file, potfile, or wordlist containing a line of exactly HCBUFSIZ_LARGE bytes.

CVE-2026-68768 (GCVE-0-2026-68768)

Vulnerability from cvelistv5 – Published: 2026-08-22 14:12 – Updated: 2026-08-24 18:31

Title

hashcat through 7.1.2 Heap Buffer Overflow in outfile_write() via Oversized Username

Summary

hashcat contains a heap-based buffer overflow (out-of-bounds write) in the outfile_write() function in src/outfile.c. When assembling output into a fixed-size buffer (HCBUFSIZ_LARGE, ~16 MB), the function sequentially appends the username, separator, hash, and plaintext via memcpy without validating that the accumulated length stays within the buffer capacity. When run with --username --show against a crafted hash file containing an oversized username that nearly fills the buffer, the total assembled output exceeds the buffer, causing a heap buffer overflow that can corrupt memory and crash the process.
