security advisorygentooarbitrary code executionGentoo: GLSA-200707-04 Normal: Glibc Integer Overflow Threat Analysis
An integer overflow in the dynamic loader, ld.so, could result in the execution of arbitrary code with escalated privileges.. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200707-04 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: GNU C Library: Integer overflow Date: July 03, 2007 Bugs: #183844 ID: 200707-04 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= An integer overflow in the dynamic loader, ld.so, could result in the execution of arbitrary code with escalated privileges. Background ========= The GNU C library is the standard C library used by Gentoo Linux systems. It provides programs with basic facilities and interfaces to system calls. ld.so is the dynamic linker which prepares dynamically linked programs for execution by resolving runtime dependencies and related functions. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-libs/glibc < 2.5-r4 > = 2.5-r4 ------------------------------------------------------------------- # Package 1 only applies to x86 users. Description ========== Tavis Ormandy of the Gentoo Linux Security Team discovered a flaw in the handling of the hardware capabilities mask by the dynamic loader. If a mask is specified with a high population count, an integer overflow could occur when allocating memory. Impact ===== As the hardware capabilities mask is honored by the dynamic loader during the execution of suid and sgid programs, in theory this vulnerability could result in theexecution of arbitrary code with root privileges. This update is provided as a precaution against currently unknown attack vectors. Workaround ========= There is no known workaround at this time. Resolution ========= All users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =sys-libs/glibc-2.5-r4" References ========= [ 1 ] CVE-2007-3508 https://www.cve.org/CVERecord?id=CVE-2007-3508 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200707-04 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.

security advisorydenial of servicegentoo linuxGentoo: 202310-12 Advisory: Apache 2 Service Disruption Vulnerabilities
Several vulnerabilities have been found in Apache 2 and mod_dav for Apache 1.3 which could allow a remote attacker to cause a Denial of Service or a local user to get escalated privileges. [More...]. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200409-21 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: Apache 2, mod_dav: Multiple vulnerabilities Date: September 16, 2004 Bugs: #62626, #63948, #64145 ID: 200409-21 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= Several vulnerabilities have been found in Apache 2 and mod_dav for Apache 1.3 which could allow a remote attacker to cause a Denial of Service or a local user to get escalated privileges. Background ========= The Apache HTTP server is one of most popular web servers on the internet. mod_ssl provides SSL v2/v3 and TLS v1 support for it and mod_dav is the Apache module for Distributed Authoring and Versioning (DAV). Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-www/apache < 2.0.51 > = 2.0.51 < 2.0 2 net-www/mod_dav = 1.0.3-r2 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description ========== A potential infinite loop has been found in the input filter of mod_ssl (CAN-2004-0748)as well as a possible segmentation fault in the char_buffer_read function if reverse proxying to a SSL server is being used (CAN-2004-0751). Furthermore, mod_dav, as shipped in Apache httpd 2 or mod_dav 1.0.x for Apache 1.3, contains a NULL pointer dereference which can be triggered remotely (CAN-2004-0809). The third issue is an input validation error found in the IPv6 URI parsing routines within the apr-util library (CAN-2004-0786). Additionally a possible buffer overflow has been reported when expanding environment variables during the parsing of configuration files (CAN-2004-0747). Impact ===== A remote attacker could cause a Denial of Service either by aborting a SSL connection in a special way, resulting in CPU consumption, by exploiting the segmentation fault in mod_ssl or the mod_dav flaw. A remote attacker could also crash a httpd child process by sending a specially crafted URI. The last vulnerabilty could be used by a local user to gain the privileges of a httpd child, if the server parses a carefully prepared .htaccess file. Workaround ========= There is no known workaround at this time. Resolution ========= All Apache 2 users should upgrade to the latest version: # emerge sync # emerge -pv "> =net-www/apache-2.0.51" # emerge "> =net-www/apache-2.0.51" All mod_dav users should upgrade to the latest version: # emerge sync # emerge -pv "> =net-www/mod_dav-1.0.3-r2" # emerge "> =net-www/mod_dav-1.0.3-r2" References ========= [ 1 ] CAN-2004-0747 https://www.cve.org/CVERecord?id=CVE-CAN-2004-0747 [ 2 ] CAN-2004-0748 https://www.cve.org/CVERecord?id=CVE-CAN-2004-0748 [ 3 ] CAN-2004-0751 https://www.cve.org/CVERecord?id=CVE-CAN-2004-0751 [ 4 ] CAN-2004-0786 https://www.cve.org/CVERecord?id=CVE-CAN-2004-0786 [ 5 ] CAN-2004-0809 https://www.cve.org/CVERecord?id=CVE-CAN-2004-0809 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200409-21 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
