http://www.kb.cert.org/vuls/id/834865 Bump to nb2. This will change the internal version of sendmail to 8.12.11.20060308. > SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server > and client side of sendmail with timeouts in the libsm I/O > layer and fix problems in that code. Also fix handling of > a buffer in sm_syslog() which could have been used as an > attack vector to exploit the unsafe handling of > setjmp(3)/longjmp(3) in combination with signals. > Problem detected by Mark Dowd of ISS X-Force. > Handle theoretical integer overflows that could triggered if > the server accepted headers larger than the maximum > (signed) integer value. This is prevented in the default > configuration by restricting the size of a header, and on > most machines memory allocations would fail before reaching > those values. Problems found by Phil Brass of ISS. |
