CVE-2011-2767 4 Apache, Canonical, Debian and 1 more 7 Mod Perl, Ubuntu Linux, Debian Linux and 4 more 2024-11-21 10.0 HIGH 9.8 CRITICAL
mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes.

The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory.
CVE-2011-2690 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 6.8 MEDIUM 8.8 HIGH

CVE-2011-2522 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2024-11-21 6.8 MEDIUM N/A
Multiple cross-site request forgery (CSRF) vulnerabilities in the Samba Web Administration Tool (SWAT) in Samba 3.x before 3.5.10 allow remote attackers to hijack the authentication of administrators for requests that (1) shut down daemons, (2) start daemons, (3) add shares, (4) remove shares, (5) add printers, (6) remove printers, (7) add user accounts, or (8) remove user accounts, as demonstrated by certain start, stop, and restart parameters to the status program.
CVE-2011-2501 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
The png_format_buffer function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 allows remote attackers to cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. NOTE: this vulnerability exists because of a CVE-2004-0421 regression. NOTE: this is called an off-by-one error by some sources.
CVE-2011-2498 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
The Linux kernel from v2.3.36 before v2.6.39 allows local unprivileged users to cause a denial of service (memory consumption) by triggering creation of PTE pages.
CVE-2011-2192 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2024-11-21 4.3 MEDIUM N/A
The Curl_input_negotiate function in http_negotiate.c in libcurl 7.10.6 through 7.21.6, as used in curl and other products, always performs credential delegation during GSSAPI authentication, which allows remote servers to impersonate clients via GSSAPI requests.
CVE-2011-2189 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 7.8 HIGH 7.5 HIGH
net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate of creation and cleanup of network namespaces, which makes it easier for remote attackers to cause a denial of service (memory consumption) via requests to a daemon that requires a separate namespace per connection, as demonstrated by vsftpd.
CVE-2011-1829 2 Canonical, Debian 2 Ubuntu Linux, Advanced Package Tool 2024-11-21 4.3 MEDIUM N/A
APT before 0.8.15.2 does not properly validate inline GPG signatures, which allows man-in-the-middle attackers to install modified packages via vectors involving lack of an initial clearsigned message.
CVE-2011-1783 5 Apache, Apple, Canonical and 2 more 5 Subversion, Mac Os X, Ubuntu Linux and 2 more 2024-11-21 4.3 MEDIUM N/A
The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is enabled, allows remote attackers to cause a denial of service (infinite loop and memory consumption) in opportunistic circumstances by requesting data.
CVE-2011-1752 5 Apache, Apple, Canonical and 2 more 5 Subversion, Mac Os X, Ubuntu Linux and 2 more 2024-11-21 5.0 MEDIUM N/A
The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion before 1.6.17, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a request for a baselined WebDAV resource, as exploited in the wild in May 2011.
CVE-2011-1593 3 Canonical, Linux, Redhat 8 Ubuntu Linux, Linux Kernel, Enterprise Linux and 5 more 2024-11-21 4.9 MEDIUM N/A
Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel before 2.6.38.4 allow local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call.
CVE-2011-1400 2 Canonical, Debian 3 Ubuntu Linux, Debian Linux, Tex-common 2024-11-21 6.8 MEDIUM N/A
The default configuration of the shell_escape_commands directive in conf/texmf.d/95NonPath.cnf in the tex-common package before 2.08.1 in Debian GNU/Linux squeeze, Ubuntu 10.10 and 10.04 LTS, and possibly other operating systems lists certain programs, which might allow remote attackers to execute arbitrary code via a crafted TeX document.
CVE-2011-1017 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 7.2 HIGH N/A
Heap-based buffer overflow in the ldm_frag_add function in fs/partitions/ldm.c in the Linux kernel 2.6.37.2 and earlier might allow local users to gain privileges or obtain sensitive information via a crafted LDM partition table.
CVE-2011-1012 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 4.9 MEDIUM N/A
The ldm_parse_vmdb function in fs/partitions/ldm.c in the Linux kernel before 2.6.38-rc6-git6 does not validate the VBLK size value in the VMDB structure in an LDM partition table, which allows local users to cause a denial of service (divide-by-zero error and OOPS) via a crafted partition table.
CVE-2011-1002 5 Avahi, Canonical, Debian and 2 more 5 Avahi, Ubuntu Linux, Debian Linux and 2 more 2024-11-21 5.0 MEDIUM N/A
avahi-core/socket.c in avahi-daemon in Avahi before 0.6.29 allows remote attackers to cause a denial of service (infinite loop) via an empty mDNS (1) IPv4 or (2) IPv6 UDP packet to port 5353. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-2244.
