computer vulnerability announce 15747

Linux kernel: bypassing ASLR via offset2lib

Synthesis of the vulnerability

An attacker, who knows only one memory address, can obtain the libc address, in order to exploit a vulnerability using the ROP (Return Oriented Programming) technique.
Impacted products: Linux.
Severity: 1/4.
Consequences: data reading.
Provenance: user account.
Creation date: 05/12/2014.
Identifiers: VIGILANCE-VUL-15747.

Description of the vulnerability

The Linux kernel uses ASLR in order to randomize memory addresses used by programs and libraries.

However, the offset between a PIE compiled application and the libc is constant for a given architecture (around 0x5b0000).

An attacker, who knows only one memory address, can therefore obtain the libc address, in order to exploit a vulnerability using the ROP (Return Oriented Programming) technique.

computer vulnerability alert 15746

OpenBSD: denial of service via PIPEX

Synthesis of the vulnerability

An attacker can send a malicious PIPEX packet to OpenBSD, in order to trigger a denial of service.
Impacted products: OpenBSD.
Severity: 2/4.
Consequences: denial of service on server, denial of service on service.
Provenance: intranet client.
Creation date: 05/12/2014.
Identifiers: VIGILANCE-VUL-15746.

Description of the vulnerability

The OpenBSD product implements the PIPEX (PPP IP EXtension) extension, which is enabled with net.pipex.enable.

However, when a malicious packet is received, a fatal error occurs in pipex_common_input(), pipex_pptp_lookup_session() or pipex_mppe_input().

An attacker can therefore send a malicious PIPEX packet to OpenBSD, in order to trigger a denial of service.

vulnerability announce CVE-2014-8106

QEMU: memory corruption via cirrus

Synthesis of the vulnerability

An attacker who is privileged in the guest system can generate a memory corruption in the host system via cirrus of QEMU, in order to trigger a denial of service, and possibly to execute code.
Impacted products: XenServer, Debian, BIG-IP Hardware, TMOS, Fedora, RHEL, SUSE Linux Enterprise Desktop, SLES, Ubuntu, Unix (platform) ~ not comprehensive.
Severity: 2/4.
Consequences: administrator access/rights, privileged access/rights, user access/rights, denial of service on server, denial of service on service, denial of service on client.
Provenance: privileged shell.
Creation date: 04/12/2014.

Description of the vulnerability

The QEMU product uses by default the hw/display/cirrus_vga.c VGA driver.

However, the blit_is_unsafe() function, does not check if the BIT BLIT (picture in picture) operation uses a size which is too large.

An attacker who is privileged in the guest system can therefore generate a memory corruption in the host system via cirrus of QEMU, in order to trigger a denial of service, and possibly to execute code.

vulnerability 15740

procmail: buffer overflow of getlline

Synthesis of the vulnerability

A local attacker can edit his ~/.procmailrc file, to generate a buffer overflow in the getlline() function of procmail, in order to trigger a denial of service, and possibly to execute code.
Impacted products: Unix (platform) ~ not comprehensive.
Severity: 2/4.
Consequences: privileged access/rights, user access/rights.
Provenance: user account.
Creation date: 04/12/2014.
Identifiers: 771958, VIGILANCE-VUL-15740.

Description of the vulnerability

The procmail program analyzes user's ~/.procmailrc file, in order to detect how to process his emails.

The backslash (\) character located at the end of a line indicates procmail that the rule is on several lines. However, if the size of reassembled data is greater than the size of the storage array (2048 bytes), an overflow of one byte occurs.

This vulnerability impacts systems where procmail is installed suid root, or when the user can edit his ~/.procmailrc file but does not have a shell access.

A local attacker can therefore edit his ~/.procmailrc file, to generate a buffer overflow in the getlline() function of procmail, in order to trigger a denial of service, and possibly to execute code.
