Redhat » Enterprise Linux Server : Security Vulnerabilities, CVEs, CVSS score between 5 and 5.99

schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 (aka krb5) before 1.11.3 does not properly validate UDP packets before sending responses, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged packet that triggers a communication loop, as demonstrated by krb_pingpong.nasl, a related issue to CVE-1999-0103.

Off-by-one error in the mod_ssl Certificate Revocation List (CRL) verification callback in Apache, when configured to use a CRL, allows remote attackers to cause a denial of service (child process crash) via a CRL that causes a buffer overflow of one null byte.

Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections.

PerlRun.pm in Apache mod_perl before 1.30, and RegistryCooker.pm in mod_perl 2.x, does not properly escape PATH_INFO before use in a regular expression, which allows remote attackers to cause a denial of service (resource consumption) via a crafted URI.

The ap_proxy_http_process_response function in mod_proxy_http.c in the mod_proxy module in the Apache HTTP Server 2.0.63 and 2.2.8 does not limit the number of forwarded interim responses, which allows remote HTTP servers to cause a denial of service (memory consumption) via a large number of interim responses.

The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.

Race condition in the cm_work_handler function in the InfiniBand driver (drivers/infiniband/core/cma.c) in Linux kernel 2.6.x allows remote attackers to cause a denial of service (panic) by sending an InfiniBand request while other request handlers are still running, which triggers an invalid pointer dereference.

PackageKit 0.6.17 allows installation of unsigned RPM packages as though they were signed which may allow installation of non-trusted packages and execution of arbitrary code.

Xen in the Linux kernel, when running a guest on a host without hardware assisted paging (HAP), allows guest users to cause a denial of service (invalid pointer dereference and hypervisor crash) via the SAHF instruction.

libxml2, as used in Google Chrome before 16.0.912.63, allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.

ImageMagick 6.7.5-7 and earlier allows remote attackers to cause a denial of service (infinite loop and hang) via a crafted image whose IFD contains IOP tags that all reference the beginning of the IDF.

Unspecified vulnerability in the Server component in Oracle MySQL 5.1.66 and earlier and 5.5.28 and earlier allows remote attackers to affect availability via unknown vectors.

Dnsmasq before 2.63test1, when used with certain libvirt configurations, replies to requests from prohibited interfaces, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed DNS query.

The format-number functionality in the XSLT implementation in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to obtain sensitive information via unspecified vectors that trigger a heap-based buffer over-read.

tuned 2.10.0 creates its PID file with insecure permissions which allows local users to kill arbitrary processes.

Unspecified vulnerability in the Server component in Oracle MySQL 5.1.66 and earlier, and 5.1.28 and earlier, allows remote authenticated users to affect confidentiality and integrity via unknown vectors related to Server Replication.

Mozilla Firefox before 18.0, Firefox ESR 10.x before 10.0.12 and 17.x before 17.0.2, Thunderbird before 17.0.2, Thunderbird ESR 10.x before 10.0.12 and 17.x before 17.0.2, and SeaMonkey before 2.15 allow remote attackers to spoof the address bar via vectors involving authentication information in the userinfo field of a URL, in conjunction with a 204 (aka No Content) HTTP status code.

The RasterImage::DrawFrameTo function in Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read and application crash) via a crafted GIF image.

The CERT_DecodeCertPackage function in Mozilla Network Security Services (NSS), as used in Mozilla Firefox before 20.0, Firefox ESR 17.x before 17.0.5, Thunderbird before 17.0.5, Thunderbird ESR 17.x before 17.0.5, SeaMonkey before 2.17, and other products, allows remote attackers to cause a denial of service (out-of-bounds read and memory corruption) via a crafted certificate.

mod_rewrite.c in the mod_rewrite module in the Apache HTTP Server 2.2.x before 2.2.25 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to execute arbitrary commands via an HTTP request containing an escape sequence for a terminal emulator.

The mod_headers module in the Apache HTTP Server 2.2.22 allows remote attackers to bypass "RequestHeader unset" directives by placing a header in the trailer portion of data sent with chunked transfer coding. NOTE: the vendor states "this is not a security issue in httpd as such."

Integer underflow in the pixman_trapezoid_valid macro in pixman.h in Pixman before 0.32.0, as used in X.Org server and cairo, allows context-dependent attackers to cause a denial of service (crash) via a negative bottom value.

Qemu before 2.0 block driver for Hyper-V VHDX Images is vulnerable to infinite loops and other potential issues when calculating BAT entries, due to missing bounds checks for block_size and logical_sector_size variables. These are used to derive other fields like 'sectors_per_block' etc. A user able to alter the Qemu disk image could ise this flaw to crash the Qemu instance resulting in DoS.

Unspecified vulnerability in the MySQL Client component in Oracle MySQL 5.5.36 and earlier and 5.6.16 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors.

Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1 before 3.6, as used in GnuTLS, allow remote attackers to cause a denial of service (out-of-bounds read) via crafted ASN.1 data.
