Summary
Fix CVE(s): CVE-2026-44186, CVE-2026-44631
Details
  • SECURITY UPDATE: Buffer underwrite in ap_regname() on crafted regular expressions in the configuration
    • debian/patches/CVE-2026-44631.patch: cast the capture-index bytes to unsigned char and reject capture group numbers greater than 1024 in ap_regname() in server/util_pcre.c, so a crafted regex in a <Directory~>, <Location~>, <Files~> or <Proxy~> section can no longer produce a negative capture index and underwrite the names array; also check the ap_regname() return value in dirsection(), urlsection() and filesection() in server/core.c and proxysection() in modules/proxy/mod_proxy.c. Upstream fix 7d9f3cfb10b0fe70df7358d26d7b1f374ea1a0cb (SVN r1935015).
