Description

libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.

Solution(s)

  • ubuntu-upgrade-curl
  • ubuntu-upgrade-libcurl3
  • ubuntu-upgrade-libcurl3-gnutls
  • ubuntu-upgrade-libcurl3-nss
  • ubuntu-upgrade-libcurl4
