Linux kernel large ICMP citations memory leak
| linux-kernel-memory-leak (12223) |  Medium Risk |
Description:
Linux kernel could allow a remote attacker to obtain sensitive information, caused by a memory leak. The IP stack in Linux kernel improperly computes the size of an ICMP citation for ICMP errors. By sending a malformed IP packet, a remote attacker can cause a memory leak to occur, which would allow the attacker to obtain sensitive information.
Platforms Affected:
- Linux, Kernel 2.0
- Linux, Kernel 2.0.1
- Linux, Kernel 2.0.10
- Linux, Kernel 2.0.11
- Linux, Kernel 2.0.12

- Linux, Kernel 2.0.20
- Linux, Kernel 2.0.21
- Linux, Kernel 2.0.22
- Linux, Kernel 2.0.23
- Linux, Kernel 2.0.24
- Linux, Kernel 2.0.25
- Linux, Kernel 2.0.26
- Linux, Kernel 2.0.27
- Linux, Kernel 2.0.28
