weakness note CVE-2014-0133

nginx: buffer overflow of SPDY

Synthesis of the vulnerability

An attacker can generate a buffer overflow in SPDY of nginx, in order to trigger a denial of service, and possibly to execute code.
Severity: 3/4.
Creation date: 18/03/2014.
Identifiers: CERTFR-2014-AVI-136, CVE-2014-0133, MDVSA-2015:094, openSUSE-SU-2014:0450-1, VIGILANCE-VUL-14441.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The nginx product can be compiled with the support of the SPDY experimental protocol.

However, if the size of data is greater than the size of the storage array, an overflow occurs in the ngx_http_spdy_state_save() function.

computer threat announce CVE-2013-7336

libvirt: NULL pointer dereference via qemuMonitorGetSpiceMigrationStatus

Synthesis of the vulnerability

An attacker can dereference a NULL pointer in qemuMonitorGetSpiceMigrationStatus of libvirt, in order to trigger a denial of service.
Severity: 2/4.
Creation date: 18/03/2014.
Identifiers: CVE-2013-7336, openSUSE-SU-2014:0593-1, USN-2209-1, VIGILANCE-VUL-14440.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The libvirt library manages SPICE (Simple Protocol for Independent Computing Environments) migrations.

However, if GetSpiceMigrationStatus() is called while qemuDomainGetBlockInfo() is also running, it does not check if a pointer is NULL, before using it.

An attacker can therefore dereference a NULL pointer in the qemuMonitorGetSpiceMigrationStatus() function of libvirt, in order to trigger a denial of service.

Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The mod_dav module can be enabled on Apache HTTP Server, to edit documents online.

When data starts by a space, they are removed. However, the size of data is not updated, so the '\0' terminator is written outside the array, which leads to a fatal error.

An attacker can therefore send a DAV WRITE query starting by spaces, in order to trigger a denial of service in mod_dav of Apache HTTP Server.

Description of the vulnerability

To define cookies, web clients use an HTTP header like:
  Cookie: name=value; name2=value2

The mod_log_config module logs HTTP queries received by Apache httpd. However, if a cookie has no value, a fatal error occurs in the log_cookie() function of the modules/loggers/mod_log_config.c file.

An attacker can therefore use a truncated cookie, in order to trigger a denial of service in mod_log_config of Apache HTTP Server.

cURL: incorrect certificate check via SChannel/Winssl

Synthesis of the vulnerability

An attacker can deceive Windows cURL users with the SChannel/Winssl backend, in order to trigger a Man-in-the-Middle.
Severity: 2/4.
Creation date: 17/03/2014.
Revision date: 18/03/2014.
Identifiers: CVE-2014-2522, SSA:2014-086-01, VIGILANCE-VUL-14437.
