-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2009.1364.2 Security Vulnerabilities in Solaris IP(7P) Module and STREAMS Framework May Lead to a Denial of Service (DoS) Condition 2 October 2009 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Solaris IP(7P) Module and STREAMS Framework Publisher: Sun Microsystems Operating System: Solaris OpenSolaris Impact/Access: Denial of Service -- Existing Account Resolution: Patch/Upgrade CVE Names: CVE-2009-3519 Original Bulletin: http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-66-263388-1 Comment: A final resolution is pending completion for Solaris 8. Revision History: October 2 2009: Added CVE Reference October 2 2009: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Solution Type: Sun Alert Solution 263388 : Security Vulnerabilities in Solaris IP(7P) Module and STREAMS Framework May Lead to a Denial of Service (DoS) Condition Bug ID: 6646890, 6646366 Product: Solaris 8 Operating System Solaris 9 Operating System Solaris 10 Operating System OpenSolaris Date of Workaround Release: 30-Sep-2009 SA Document Body Security Vulnerabilities in Solaris IP(7P) Module and STREAMS Framework May Lead to a Denial of Service (DoS) Condition 1. Impact Security vulnerabilities in the Solaris IP(7P) module and STREAMS Framework may allow an unprivileged local user to leak kernel memory, eventually causing the system to hang. This is a type of Denial of Service (DoS). 2. Contributing Factors These issues can occur in the following releases: SPARC Platform * Solaris 8 * Solaris 9 without patch 122300-44 * Solaris 10 without patch 141414-09 * OpenSolaris based upon builds snv_01 though snv_108 x86 Platform * Solaris 8 * Solaris 9 without patch 122301-44 * Solaris 10 without patch 141415-09 * OpenSolaris based upon builds snv_01 though snv_108 Note: Solaris 8 entered EOSL Phase 2 on 1 April 2009. Entitlement to patches developed on or after 1 April 2009 requires the purchase of the Solaris 8 Vintage Patch Service. See Note in section 5 for more details. OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. To determine the base build of OpenSolaris, the following command can be used: $ uname -v snv_108 3. Symptoms 1. If the described issue occurs, the following messages may be displayed on the system console or in the '/var/adm/messages' file: sshd: [ID <id#> auth.error] error: fork: Error 0 WARNING: /etc/svc/volatile: File system full, swap space limit exceeded WARNING: Sorry, no swap space to grow stack for pid <pid#> inetd: [ID <id#> daemon.error] Unable to fork inetd_start method of instance svc:/network/vnetd/tcp:default: Not enough space Cannot map /lib/ld.so.1 2. A forced coredump generated from unresponsive systems which have the 'kmem_flags' variable set to 0xf in the '/etc/system' file (see system(4) for modifying this file) may show memory leaks in one of the streams_dblk_* memory caches, and also in the streams_mblk cache, with one of the following stacks: kmem_cache_alloc+0x18c allocb+0x94 allocb_cred+8 strmakedata+0xa0 strput+0x23c strwrite_common+0x284 fop_write+0x20 write+0x268 kmem_cache_alloc+0x88 dblk_constructor+0x54 kmem_cache_alloc_debug+0x388 kmem_cache_alloc+0x88 allocb+0x4c allocb_tryhard+0x1c putnextctl1+0x30 ldterm_dosig+0x16c ldtermrput+0x508 putnext+0x3f4 qdrain_syncq+0x368 drain_syncq+0x618 taskq_d_thread+0xbc The following command can be run as "root" user to find memory leaks in the coredump files: # echo ::findleaks -dv | /usr/bin/mdb -k unix.# vmcore.# > findleak.txt (Where # is the current core dump number). Open findleak.txt to confirm the above stack trace. 4. Workaround There is no workaround for these issues. Please see the "Resolution" section below. 5. Resolution These issues are addressed in the following releases: SPARC Platform * Solaris 9 with patch 122300-44 or later * Solaris 10 with patch 141414-09 or later * OpenSolaris based upon builds snv_109 or later x86 Platform * Solaris 9 with patch 122301-44 or later * Solaris 10 with patch 141415-09 or later * OpenSolaris based upon builds snv_109 or later A final resolution is pending completion for Solaris 8. Note: The READMEs of Solaris 8 patches developed on or after 1 April 2009 are available to all customers. However, Solaris 8 entered EOSL Phase 2 on April 1, 2009 and thus entitlement for these patches, including those that fix security vulnerabilities, requires the purchase of the Solaris 8 Vintage Patch Service.
