Topic :

possible memory leak in zlib compression

SecurityAlert : 3981

CVE : CVE-2008-1678

CWE : CWE-399

SecurityRisk : Medium Security Risk Medium

(About)

Remote Exploit : Yes

Local Exploit : No

Victim interaction required : No

Exploit Available : No

Credit : Dustin Kirkland

Published : 12.07.2008

Affected Software :

Openssl, Openssl, 0.9.8f
Openssl, Openssl, 0.9.8g
Openssl, Openssl, 0.9.8h

Advisory Content :

I'm trying to solve a reproducible memory leak that manifests itself
with SSL + Apache2:
https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/224945

Valgrind, plus our own research, points to a possible memory leak in
crypto/comp/c_zlib.c in libssl0.9.8g.

We see:
struct zlib_state *state = -> (struct zlib_state
*)OPENSSL_malloc(sizeof(struct zlib_state));
allocating the data.

However, it does not seem that a zlib_stateful_free_ex_data() is called
to free it.

Thanks,
:-Dustin
