Pardus Linux Security Advisory 2009-84  

      Date: 2009-05-27
  Severity: 3
      Type: Local

Some vulnerabilities and weaknesses have been reported in Pidgin, which

can be exploited by malicious people to cause a DoS (Denial of Service)
or to potentially compromise a user's system.

1) A truncation error in the processing of  MSN  SLP  messages  can  be

exploited to cause a buffer overflow.

2) A boundary  error  in  the  XMPP  SOCKS5  "bytestream"  server  when
initiating an outgoing file transfer can be exploited to cause a buffer

Successful exploitation of vulnerabilities #1 and #2 may allow execution
of arbitrary code.

3)  A boundary   error   exists   in   the   implementation   of   the
"PurpleCircBuffer" structure. This can be exploited to  corrupt  memory

and cause a crash via specially crafted XMPP or Sametime packets.

4) A boundary error in the "decrypt_out()" function can be exploited to
cause  a stack-based  buffer  overflow  with  8  bytes  and  crash  the

application via a specially crafted QQ packet.

Affected packages:

  Pardus 2008:
    pidgin, all before 2.5.6-30-11

There are update(s) for pidgin. You can update them via Package Manager

or with a single command from console:

    pisi up pidgin
