| Id | Description |
|---|---|
| 6601 | OpenSSH *realloc() Unspecified Memory Errors OpenSSH contains memory flaws with unspecified consequences. The issue is triggered when *realloc() is called. No further information has been provided. |
| 3456 | OpenSSH buffer_append_space() Heap Corruption A remote overflow exists in the buffer_append_space of buffer.c in OpenSSH. OpenSSH fails to check the amount of memory being freed, resulting in a buffer overflow. With a specially crafted request, an attacker can cause denial of service or execution of arbitrary code, resulting in a loss of integrity and/or availability. |
| 2557 | OpenSSH Multiple Buffer Management Multiple Overflows OpenSSH contains several flaws that may allow remote attackers to execute arbitrary code. The issues occur in the buffer_init and buffer_free functions in buffer.c, as well as an separate function also called buffer_free in channels.c. These functions may provide an attacker with the opportunity to inject custom data that could result in memory manipulation and possibly code execution. |
