CVE-2026-76651 Média · 5.3 CWE-120 28/08/2026

Pre-Authentication Multipart Boundary Buffer Overflow in HTTP Service in TP-Link TL-WR841N

A buffer overflow vulnerability exists in the embedded HTTP service in TL-WR841N v14 when processing multipart/form-data requests. Insufficient validation of an attacker-controlled boundary parameter may allow a remote unauthenticated attacker to submit a crafted request that corrupts memory by overwriting data beyond the bounds of an internal buffer. Successful exploitation may result in modification or corruption of process memory, potentially leading to undefined application behavior. Arbitrary code execution, information disclosure, and denial-of-service conditions have not been demonstrated.

Gimp: heap out-of-bounds read and stack out-of-bounds access in psd loader from channel-count handling

A flaw was found in the file-psd plugin in GIMP. When processing a specially crafted PSD image file, the plugin does not properly validate the channel-count parameter. This incorrect validation leads to improper memory bounds checking, resulting in both a heap out-of-bounds read and a stack out-of-bounds access. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of memory contents.

CVE-2026-78322 Média · 6.5 CWE-120 25/08/2026

File-roller: file-roller: stack buffer overflow in parse_progress_line for 7z and rar handlers

A flaw was found in file-roller. When opening or extracting a malicious 7z or RAR archive containing a file entry with an excessively long path, file-roller's progress-line parsing copies the path into a fixed-size stack buffer using an unbounded string copy. This can trigger a stack buffer overflow and cause file-roller to terminate, resulting in a denial of service. To exploit this flaw, a victim must open or extract the crafted archive using file-roller.

CVE-2026-68768 Média · 6.1 CWE-120 22/08/2026

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

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.
