computer vulnerability note CVE-2014-4508

Linux kernel: denial of service via CONFIG_AUDITSYSCALL

Synthesis of the vulnerability

A local attacker can use a system call on a Linux kernel with CONFIG_AUDITSYSCALL, in order to trigger a denial of service.
Impacted products: Fedora, Linux, openSUSE, SUSE Linux Enterprise Desktop, SLES, Ubuntu.
Severity: 1/4.
Consequences: denial of service on server.
Provenance: user shell.
Creation date: 20/06/2014.
Identifiers: CERTFR-2014-AVI-373, CERTFR-2014-AVI-388, CVE-2014-4508, FEDORA-2014-7863, FEDORA-2014-8487, openSUSE-SU-2014:0957-1, openSUSE-SU-2014:0985-1, openSUSE-SU-2014:1246-1, openSUSE-SU-2014:1669-1, openSUSE-SU-2014:1677-1, openSUSE-SU-2015:0566-1, SUSE-SU-2014:0908-1, SUSE-SU-2014:0909-1, SUSE-SU-2014:1105-1, SUSE-SU-2014:1138-1, SUSE-SU-2014:1316-1, SUSE-SU-2014:1319-1, SUSE-SU-2014:1693-1, SUSE-SU-2014:1693-2, SUSE-SU-2014:1695-1, SUSE-SU-2014:1695-2, SUSE-SU-2014:1698-1, USN-2332-1, USN-2333-1, USN-2334-1, USN-2336-1, USN-2337-1, VIGILANCE-VUL-14919.

Description of the vulnerability

The Linux kernel can be compiled with CONFIG_AUDITSYSCALL, in order to audit system calls.

However, the arch/x86/kernel/entry_32.S file does not check if the system call number is too large, which stops the kernel.

A local attacker can therefore use a system call on a Linux kernel with CONFIG_AUDITSYSCALL, in order to trigger a denial of service.

computer vulnerability bulletin CVE-2014-3494

kdelibs: man-in-the-middle via POP3 kioslave

Synthesis of the vulnerability

An attacker can act as a man-in-the-middle between KMail and a POP3 server, in order to read or alter data.
Impacted products: Fedora, openSUSE, Unix (platform) ~ not comprehensive.
Severity: 2/4.
Consequences: data reading, data creation/edition.
Provenance: internet server.
Creation date: 19/06/2014.
Identifiers: CVE-2014-3494, FEDORA-2014-7572, FEDORA-2014-7579, openSUSE-SU-2015:0573-1, VIGILANCE-VUL-14918.

Description of the vulnerability

The KMail/KIO product uses the kdelibs library.

The POP3 kioslave is used by KMail to connect to a POP3 messaging server. However, if the certificate of the secured POP3 server changed, the error does not flow to KMail, so the user is not warned.

An attacker can therefore act as a man-in-the-middle between KMail and a POP3 server, in order to read or alter data.
