Detail

A security issue affects the following Ubuntu releases:

Ubuntu 5.04 Ubuntu 5.10 Ubuntu 6.06 LTS

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 5.04:
libssl0.9.7 0.9.7e-3ubuntu0.4

Ubuntu 5.10:
libssl0.9.7 0.9.7g-1ubuntu1.3

Ubuntu 6.06 LTS:
libssl0.9.8 0.9.8a-7ubuntu0.2

After a standard system upgrade you need to reboot your computer to effect the necessary changes.

Details follow:

Dr. Henson of the OpenSSL core team and Open Network Security discovered a mishandled error condition in the ASN.1 parser. By sending specially crafted packet data, a remote attacker could exploit this to trigger an infinite loop, which would render the service unusable and consume all available system memory. (CVE-2006-2937)

Certain types of public key could take disproportionate amounts of time to process. The library now limits the maximum key exponent size to avoid Denial of Service attacks. (CVE-2006-2940)

Tavis Ormandy and Will Drewry of the Google Security Team discovered a buffer overflow in the SSL_get_shared_ciphers() function. By sending specially crafted packets to applications that use this function (like Exim, MySQL, or the openssl command line tool), a remote attacker could exploit this to execute arbitrary code with the server's privileges. (CVE-2006-3738)

Tavis Ormandy and Will Drewry of the Google Security Team reported that the get_server_hello() function did not sufficiently check the client's session certificate. This could be exploited to crash clients by remote attackers sending specially crafted SSL responses. (CVE-2006-4343)

Id Description
29263 OpenSSL SSLv2 get_server_hello Function Remote DoS

OpenSSL contains a flaw that may allow a remote denial of service. The issue is triggered when an unspecified error occurs in the get_server_hello function, and will result in loss of availability for the client.
29262 OpenSSL SSL_get_shared_ciphers Function Unspecified Remote Overflow

A remote overflow exists in OpenSSL. OpenSSL contains an unspecified issue in the SSL_get_shared_ciphers function. With a specially crafted request, an attacker can cause an unspecified impact.
29261 OpenSSL Crafted Public Key CPU Consumption DoS

OpenSSL contains a flaw that may allow a remote denial of service. The issue is triggered when large values in X.509 certificates require extra time to process, and may result in loss of availability for the service.
29260 OpenSSL Malformed ASN.1 Structure Resource Consumption DoS

OpenSSL contains a flaw that may allow a remote denial of service. The issue is triggered due to an error in processing malformed ASN.1 structures which may lead to infinite loop and consumption of memory, and will result in loss of availability for the service.
