SB2012091202 - SUSE Linux update for compat-openssl097g

Description

This security bulletin contains information about 2 secuirty vulnerabilities.

1) Buffer overflow (CVE-ID: CVE-2012-2110)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1 before 1.0.1a does not properly interpret integer data, which allows remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key.

2) Input validation error (CVE-ID: CVE-2012-2131)

The vulnerability allows remote attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key.

Remediation
