Linux kernel multiple security vulnerabilities
updated since 11.08.2014
Published:18.08.2014
Source:
SecurityVulns ID:13914
Type:local
Threat Level:
7/10
Description:DoS via ptrace syscall, filesystems mount options limitation bypass.
Affected:LINUX : kernel 3.15
CVE:CVE-2014-5207 (fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a "mount -o remount" command within a user namespace.)
 CVE-2014-5206 (The do_remount function in fs/namespace.c in the Linux kernel through 3.16.1 does not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allows local users to bypass an intended read-only restriction and defeat certain sandbox protection mechanisms via a "mount -o remount" command within a user namespace.)
 CVE-2014-4699 (The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls.)

Apache HttpClient certificate checking bypass
Published:18.08.2014
Source:
SecurityVulns ID:13923
Type:library
Threat Level:
6/10
Description:Validation bypass via malcrafted constructions like O="foo,CN=www.apache.org”
Affected:APACHE : Apache HttpComponents 4.3
CVE:CVE-2014-3577 (org.apache.http.conn.ssl.AbstractVerifier in Apache HttpComponents HttpClient before 4.3.5 and HttpAsyncClient before 4.0.2 does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a "CN=" string in a field in the distinguished name (DN) of a certificate, as demonstrated by the "foo,CN=www.apache.org" string in the O field.)

CVE:CVE-2014-5239 (The Microsoft Outlook.com application before 7.8.2.12.49.7090 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.)
