Description:
A vulnerability was reported in OpenSSL. A remote user can consume excessive CPU resources on the target system. IBM Security Access Manager is affected.
The ssl3_read_bytes() function in 'ssl/s3_pkt.c' does not properly handle certain packets. A remote user can send a flood of SSL3_AL_WARNING alerts during the SSL handshake to consume excessive CPU resources on the target system. As a result, services that use the OpenSSL library may become unavailable for the duration of the packet flood.
Shi Lei from Gear Team, Qihoo 360 Inc., reported this vulnerability.
