Gaim Extract Info Field function stack overflow
| gaim-extractinfo-bo (14946) |  High Risk |
Description:
Gaim is vulnerable to a stack overflow in the gaim_markup_extract_info_field function, which is used by the MSN and YMSG protocol handlers. This function combines data from two tokens into a fixed-length stack buffer without properly checking the size of the resulting string. A remote attacker can supply a specially-crafted set of data to overflow the stack and possibly execute arbitrary code on the system.
