OpenSSL DoS confitions
SecurityVulns ID:10780
Threat Level:
Description:DoS conditions in ssl3_get_record and kssl_keytab_is_available functions.
Affected:OPENSSL : OpenSSL 0.9
CVE:CVE-2010-0740 (The ssl3_get_record function in ssl/s3_pkt.c in OpenSSL 0.9.8f through 0.9.8m allows remote attackers to cause a denial of service (crash) via a malformed record in a TLS connection that triggers a NULL pointer dereference, related to the minor version number. NOTE: some of these details are obtained from third party information.)
 CVE-2010-0433 (The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but Kerberos configuration files cannot be opened, does not check a certain return value, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via SSL cipher negotiation, as demonstrated by a chroot installation of Dovecot or stunnel without Kerberos configuration files inside the chroot.)

SecurityVulns ID:10781

sudo protection bypass
updated since 01.03.2010
SecurityVulns ID:10655
Threat Level:
Description:when a pseudocommand is enabled, it's possible to created an executable file with the same name, it will be executed by relative name with escalated privileges.
CVE:CVE-2010-1163 (The command matching functionality in sudo 1.6.8 through 1.7.2p5 does not properly handle when a file in the current working directory has the same name as a pseudo-command in the sudoers file and the PATH contains an entry for ".", which allows local users to execute arbitrary commands via a Trojan horse executable, as demonstrated using sudoedit, a different vulnerability than CVE-2010-0426.)
 CVE-2010-0426 (sudo 1.6.x before 1.6.9p21 and 1.7.x before 1.7.2p4, when a pseudo-command is enabled, permits a match between the name of the pseudo-command and the name of an executable file in an arbitrary directory, which allows local users to gain privileges via a crafted executable file, as demonstrated by a file named sudoedit in a user's home directory.)
