Canonical » Ubuntu Linux : Security Vulnerabilities, CVEs, Published In May 2015

racoon/gssapi.c in IPsec-Tools 0.8.2 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon crash) via a series of crafted UDP requests.

The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.

The _clone function in XML::LibXML before 2.0119 does not properly set the expand_entities option, which allows remote attackers to conduct XML external entity (XXE) attacks via crafted XML data to the (1) new or (2) load_xml function.

Untrusted search path vulnerability in Module::Signature before 0.75 allows local users to gain privileges via a Trojan horse module under the current working directory, as demonstrated by a Trojan horse Text::Diff module.

Module::Signature before 0.74 allows remote attackers to execute arbitrary shell commands via a crafted SIGNATURE file which is not properly handled when generating checksums from a signed manifest.

Module::Signature before 0.74 allows remote attackers to bypass signature verification for files via a signature file that does not list the files.

The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket.

Double free vulnerability in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 allows remote attackers to cause a denial of service (crash) by closing an SSL session at a time when the authentication timeout will expire during the session shutdown sequence.

The default configuration for cURL and libcurl before 7.42.1 sends custom HTTP headers to both the proxy and destination server, which might allow remote proxy servers to obtain sensitive information by reading the header contents.

arch/x86/kernel/entry_64.S in the Linux kernel before 3.19.2 does not prevent the TS_COMPAT flag from reaching a user-mode task, which might allow local users to bypass the seccomp or audit protection mechanism via a crafted application that uses the (1) fork or (2) close system call, as demonstrated by an attack against seccomp before 3.16.

ClamAV before 0.98.7 allows remote attackers to cause a denial of service (infinite loop) via a crafted xz archive file.

ClamAV before 0.98.7 allows remote attackers to cause a denial of service (crash) via a crafted petite packed file.

ClamAV before 0.98.7 allows remote attackers to cause a denial of service (infinite loop) via a crafted y0da cryptor file.

The upx decoder in ClamAV before 0.98.7 allows remote attackers to cause a denial of service (crash) via a crafted file.

Multiple unspecified vulnerabilities in Google Chrome before 42.0.2311.135 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

Use-after-free vulnerability in the MutationObserver::disconnect function in core/dom/MutationObserver.cpp in the DOM implementation in Blink, as used in Google Chrome before 42.0.2311.135, allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering an attempt to unregister a MutationObserver object that is not currently registered.

nbd-server.c in Network Block Device (nbd-server) before 3.11 does not properly handle signals, which allows remote attackers to cause a denial of service (deadlock) via unspecified vectors.
