Title: Multiple Linux Vendor IP Options Vulnerability
Severity: MODERATE
Description:
A vulnerability in the Linux Kernel's IPv4 option processing may allow a remote user to crash the system.
The vulnerability is the result of the kernel freeing a socket buffer when it shouldn't while sending an ICMP Parameter Problem error message in response to an IP packet with a malformed IP option. This results in the buffer being freed twice and in memory corruption.
Of the Debian Linux 2.1 supported architectures only the SPARC one is vulnerable.
Affected Products:
- Debian Linux 2.1.0
- Linux kernel 2.2.0
- Linux kernel 2.3.0
- RedHat Linux 6.0.0
- S.u.S.E. Linux 6.1.0
