[slackware-security]  mutt (SSA:2026-186-01)

New mutt packages are available for Slackware 15.0 and -current to
fix a security issue.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/mutt-2.4.1-i586-1_slack15.0.txz:  Upgraded.
  This update fixes a security issue:
  Prevent unsigned int overflow in imap_cmd_step buffer growth.
  The idata->blen field is unsigned int (32-bit) while the companion
  variable len is size_t (64-bit on LP64). When a malicious IMAP server
  sends a response line longer than UINT_MAX bytes without newline, the
  expression wraps to a small value, causing safe_realloc() to shrink the
  buffer while len retains its original huge value. The subsequent
  mutt_socket_readln() then writes far past the shrunken allocation.
  Fix by changing idata->blen from unsigned int to size_t, matching the
  type of len and preventing the overflow on all platforms.
  (* Security fix *)
