XORP (eXtensible Open Router Platform) 1.2 and 1.3 allows remote attackers to cause a denial of service (application crash) via an Open Shortest Path First (OSPF) Link State Advertisement (LSA) with an invalid LSA length field.

XORP (eXtensible Open Router Platform) 1.2 and 1.3 allows remote attackers to cause a denial of service (application crash) via an Open Shortest Path First (OSPF) Link State Advertisement (LSA) with an invalid LSA length field.

XORP (eXtensible Open Router Platform) 1.2 and 1.3 allows remote attackers to cause a denial of service (application crash) via an Open Shortest Path First (OSPF) Link State Advertisement (LSA) with an invalid LSA length field. Exploiting this issue allows remote, unauthenticated attackers to crash the application, denying further service to legitimate users. eXtensible Open Router Platform versions 1.2 and 1.3 are vulnerable to this issue.

TITLE: XORP OSPF Link State Advertisements Denial of Service

SECUNIA ADVISORY ID: SA22462

VERIFY ADVISORY: http://secunia.com/advisories/22462/

CRITICAL: Moderately critical

IMPACT: DoS

WHERE: >From remote

SOFTWARE: XORP 1.x http://secunia.com/product/12372/

DESCRIPTION: Mu Security has reported a vulnerability in XORP, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an out of bounds read when processing Link State Advertisements (LSA). This can be exploited to crash the OSPF daemon by sending LSAs with invalid length values.

The vulnerabili…
