From 4e8c6f340751c66a602b98b727af28b2a9004313 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich <jo@mein.io> Date: Fri, 12 Aug 2016 11:44:07 +0200 Subject: [PATCH] dropbear: security update to 2016.74 - Security: Message printout was vulnerable to format string injection. If specific usernames including "%" symbols can be created on a system (validated by getpwnam()) then an attacker could run arbitrary code as root when connecting to Dropbear server. A dbclient user who can control username or host arguments could potentially run arbitrary code as the dbclient user. This could be a problem if scripts or webpages pass untrusted input to the dbclient program. - Security: dropbearconvert import of OpenSSH keys could run arbitrary code as the local dropbearconvert user when parsing malicious key files - Security: dbclient could run arbitrary code as the local dbclient user if particular -m or -c arguments are provided. This could be an issue where dbclient is used in scripts. - Security: dbclient or dropbear server could expose process memory to the running user if compiled with DEBUG_TRACE and running with -v The security issues were reported by an anonymous researcher working with Beyond Security's SecuriTeam Secure Disclosure www.beyondsecurity.com/ssd.html Signed-off-by: Jo-Philipp Wich <jo@mein.io> --- package/network/services/dropbear/Makefile | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/package/network/services/dropbear/Makefile b/package/network/services/dropbear/Makefile index 9d62e926b4..36bcb4ab7b 100644 --- a/package/network/services/dropbear/Makefile +++ b/package/network/services/dropbear/Makefile @@ -8,14 +8,14 @@ include $(TOPDIR)/rules.mk PKG_NAME:=dropbear -PKG_VERSION:=2016.73 +PKG_VERSION:=2016.74 PKG_RELEASE:=1 PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.bz2 PKG_SOURCE_URL:= \ http://matt.ucc.asn.au/dropbear/releases/ \ https://dropbear.nl/mirror/releases/ -PKG_MD5SUM:=8d6d78ce60ca52350ec04fcbd711ce9b +PKG_MD5SUM:=9ad0172731e0f16623937804643b5bd8 PKG_LICENSE:=MIT PKG_LICENSE_FILES:=LICENSE libtomcrypt/LICENSE libtommath/LICENSE -- GitLab
