Summary Content-length DOS (malloc error)
Date 2004-08-26
Discovered By Sean (infamous42md)
Fixed In Release 0.82

Description

Remote crash. When a remote server provides a large content-length header value, Gaim will attempt to allocate a buffer to store the content, however this allocation attempt will cause Gaim to crash if the length exceeds the amount of possible memory. This happens when reading profile information on some protocols. It also happens when smiley themes are installed via drag and drop.

Mitigation

The call to g_malloc() was replaced with a call to g_try_malloc(). If the memory could not be allocated the function returns instead of causing the application to crash.
