Doc Text:
A flaw was found in GoAccess, a real-time web log analyzer. A remote attacker could exploit this vulnerability by providing a specially crafted User-Agent string in an access log. This improper handling by the `parse_browser()` function leads to a heap out-of-bounds write, a type of memory corruption. Successful exploitation could corrupt application memory or crash GoAccess, resulting in a denial of service.

Description OSIDB Bzimport 2026-07-30 21:01:55 UTC
GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through the browser. In version 1.10.2, parse_browser assumes the matched browser token begins with Opera and moves a trailing version substring to match plus five, allowing a crafted User-Agent in a processed access log to write one to four attacker-influenced bytes beyond the heap allocation and corrupt or crash GoAccess. This issue is fixed in version 1.11.
