Detail
| A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) The following packages are affected: ppp The problem can be corrected by upgrading the affected packages to version 2.4.2+20040428-2ubuntu6.2. In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: It has been discovered that ppp does not properly verify certain data structures used in the CBCP protocol. This vulnerability could allow an attacker to cause the pppd server to crash due to an invalid memory access, leading to a denial of service. However, there is no possibility of code execution or privilege escalation. |

| 11178 | pppd Malformed CBCP Packet Remote DoS A remote overflow exists in Samba's PPP implementation. It was reported that an attacker could take advantage of an integer underflow in the cbcp_input() function of cbcp.c to deny service to the server. Subsequent reports indicated that this flaw could only be used to disconnect the attacker's own PPP session, not the sessions of other users. |
