teTeX makeindex open_sty function buffer overflow
|tetex-makeindex-opensty-bo (32284)||High Risk|
teTeX makeindex is vulnerable to a buffer overflow, caused by improper bounds checking by the open_sty function. By persuading a victim to open a file with an overly long filename, a remote attacker could overflow a buffer and cause makeindex to crash or possibly execute arbitrary code on the system.
