Summary
Fix CVE(s): CVE-2026-44631
Details
  • SECURITY UPDATE: buffer underwrite in ap_regname() via crafted regular expressions in the configuration
    • debian/patches/CVE-2026-44631.patch: cast the PCRE name-table capture index bytes to unsigned char in ap_regname() in server/util_pcre.c so a high bit no longer sign-extends the capture index to a negative value, and reject capture group numbers above 1024 by returning an error that the // and configuration handlers in server/core.c and modules/proxy/mod_proxy.c now check, preventing a buffer underwrite. Upstream fix 7d9f3cfb10b0fe70df7358d26d7b1f374ea1a0cb (SVN r1935015).
