CVE-2008-1887 3 Canonical, Debian, Python 3 Ubuntu Linux, Debian Linux, Python 2025-04-09 9.3 HIGH N/A
Python 2.5.2 and earlier allows context-dependent attackers to execute arbitrary code via multiple vectors that cause a negative size value to be provided to the PyString_FromStringAndSize function, which allocates less memory than expected when assert() is disabled and triggers a buffer overflow.
CVE-2009-1961 5 Canonical, Debian, Linux and 2 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2025-04-09 1.9 LOW 4.7 MEDIUM
The inode double locking code in fs/ocfs2/file.c in the Linux kernel 2.6.30 before 2.6.30-rc3, 2.6.27 before 2.6.27.24, 2.6.29 before 2.6.29.4, and possibly other versions down to 2.6.19 allows local users to cause a denial of service (prevention of file creation and removal) via a series of splice system calls that trigger a deadlock between the generic_file_splice_write, splice_from_pipe, and ocfs2_file_splice_write functions.
CVE-2009-0949 5 Apple, Canonical, Debian and 2 more 7 Cups, Mac Os X, Mac Os X Server and 4 more 2025-04-09 5.0 MEDIUM 7.5 HIGH
The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10 does not properly initialize memory for IPP request packets, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a scheduler request with two consecutive IPP_TAG_UNSUPPORTED tags.
CVE-2007-2443 3 Canonical, Debian, Mit 3 Ubuntu Linux, Debian Linux, Kerberos 5 2025-04-09 8.3 HIGH N/A
Integer signedness error in the gssrpc__svcauth_unix function in svc_auth_unix.c in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a negative length value.
CVE-2009-3001 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2025-04-09 4.9 MEDIUM N/A
The llc_ui_getname function in net/llc/af_llc.c in the Linux kernel 2.6.31-rc7 and earlier does not initialize a certain data structure, which allows local users to read the contents of some kernel memory locations by calling getsockname on an AF_LLC socket.
CVE-2007-2875 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-04-09 2.1 LOW N/A
Integer underflow in the cpuset_tasks_read function in the Linux kernel before 2.6.20.13, and 2.6.21.x before 2.6.21.4, when the cpuset filesystem is mounted, allows local users to obtain kernel memory contents by using a large offset when reading the /dev/cpuset/tasks file.
CVE-2006-6811 2 Canonical, Kde 2 Ubuntu Linux, Ksirc 2025-04-09 4.3 MEDIUM 6.5 MEDIUM
KsIRC 1.3.12 allows remote attackers to cause a denial of service (crash) via a long PRIVMSG string when connecting to an Internet Relay Chat (IRC) server, which causes an assertion failure and results in a NULL pointer dereference. NOTE: this issue was originally reported as a buffer overflow.
CVE-2008-3281 7 Apple, Canonical, Debian and 4 more 11 Iphone Os, Safari, Ubuntu Linux and 8 more 2025-04-09 4.3 MEDIUM 6.5 MEDIUM
libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.
CVE-2008-0166 3 Canonical, Debian, Openssl 3 Ubuntu Linux, Debian Linux, Openssl 2025-04-09 7.8 HIGH 7.5 HIGH
OpenSSL 0.9.8c-1 up to versions before 0.9.8g-9 on Debian-based operating systems uses a random number generator that generates predictable numbers, which makes it easier for remote attackers to conduct brute force guessing attacks against cryptographic keys.
CVE-2007-4476 3 Canonical, Debian, Gnu 3 Ubuntu Linux, Debian Linux, Tar 2025-04-09 7.5 HIGH N/A
Buffer overflow in the safer_name_suffix function in GNU tar has unspecified attack vectors and impact, resulting in a "crashing stack."
CVE-2009-1185 7 Canonical, Debian, Fedoraproject and 4 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2025-04-09 7.2 HIGH N/A
udev before 1.4.1 does not verify whether a NETLINK message originates from kernel space, which allows local users to gain privileges by sending a NETLINK message from user space.
CVE-2007-3798 6 Apple, Canonical, Debian and 3 more 7 Mac Os X, Mac Os X Server, Ubuntu Linux and 4 more 2025-04-09 6.8 MEDIUM 9.8 CRITICAL
Integer overflow in print-bgp.c in the BGP dissector in tcpdump 3.9.6 and earlier allows remote attackers to execute arbitrary code via crafted TLVs in a BGP packet, related to an unchecked return value.
CVE-2009-2474 4 Apple, Canonical, Fedoraproject and 1 more 4 Mac Os X, Ubuntu Linux, Fedora and 1 more 2025-04-09 5.8 MEDIUM N/A
neon before 0.28.6, when OpenSSL or GnuTLS is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
CVE-2008-2726 3 Canonical, Debian, Ruby-lang 3 Ubuntu Linux, Debian Linux, Ruby 2025-04-09 7.8 HIGH N/A
Integer overflow in the (1) rb_ary_splice function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2; and (2) the rb_ary_replace function in 1.6.x allows context-dependent attackers to trigger memory corruption, aka the "beg + rlen" issue. NOTE: as of 20080624, there has been inconsistent usage of multiple CVE identifiers related to Ruby. The CVE description should be regarded as authoritative, although it is likely to change.
CVE-2007-1864 4 Canonical, Debian, Php and 1 more 5 Ubuntu Linux, Debian Linux, Php and 2 more 2025-04-09 7.5 HIGH N/A
Buffer overflow in the bundled libxmlrpc library in PHP before 4.4.7, and 5.x before 5.2.2, has unknown impact and remote attack vectors.
CVE-2008-4577 4 Canonical, Dovecot, Fedoraproject and 1 more 4 Ubuntu Linux, Dovecot, Fedora and 1 more 2025-04-09 6.4 MEDIUM 7.5 HIGH
The ACL plugin in Dovecot before 1.1.4 treats negative access rights as if they are positive access rights, which allows attackers to bypass intended access restrictions.
CVE-2007-3304 4 Apache, Canonical, Fedoraproject and 1 more 6 Http Server, Ubuntu Linux, Fedora and 3 more 2025-04-09 4.7 MEDIUM N/A
Apache httpd 1.3.37, 2.0.59, and 2.2.4 with the Prefork MPM module, allows local users to cause a denial of service by modifying the worker_score and process_score arrays to reference an arbitrary process ID, which is sent a SIGUSR1 signal from the master process, aka "SIGUSR1 killer."
CVE-2007-2728 2 Canonical, Php 2 Ubuntu Linux, Php 2025-04-09 5.0 MEDIUM N/A
The soap extension in PHP calls php_rand_r with an uninitialized seed variable, which has unknown impact and attack vectors, a related issue to the mcrypt_create_iv issue covered by CVE-2007-2727. Note: The PHP team argue that this is not a valid security issue.
CVE-2007-2444 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2025-04-09 7.2 HIGH N/A
Logic error in the SID/Name translation functionality in smbd in Samba 3.0.23d through 3.0.25pre2 allows local users to gain temporary privileges and execute SMB/CIFS protocol operations via unspecified vectors that cause the daemon to transition to the root user.
CVE-2008-3529 4 Apple, Canonical, Debian and 1 more 6 Iphone Os, Mac Os X, Safari and 3 more 2025-04-09 10.0 HIGH N/A
Heap-based buffer overflow in the xmlParseAttValueComplex function in parser.c in libxml2 before 2.7.0 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a long XML entity name.
