Fedoraproject » Fedora » 23 : Security Vulnerabilities, CVEs, Published In 2016

Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.

Integer overflow in the opj_pi_create_decode function in pi.c in OpenJPEG allows remote attackers to execute arbitrary code via a crafted JP2 file, which triggers an out-of-bounds read or write.

Eye of GNOME (aka eog) 3.16.5, 3.17.x, 3.18.x before 3.18.3, 3.19.x, and 3.20.x before 3.20.4, when used with glib before 2.44.1, allow remote attackers to cause a denial of service (out-of-bounds write and crash) via vectors involving passing invalid UTF-8 to GMarkup.

The makecontext function in the GNU C Library (aka glibc or libc6) before 2.25 creates execution contexts incompatible with the unwinder on ARM EABI (32-bit) platforms, which might allow context-dependent attackers to cause a denial of service (hang), as demonstrated by applications compiled using gccgo, related to backtrace generation.

Heap-based buffer overflow in the parse_packet function in network.c in collectd before 5.4.3 and 5.x before 5.5.2 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted network packet.

The XSLoader::load method in XSLoader in Perl does not properly locate .so files when called in a string eval, which might allow local users to execute arbitrary code via a Trojan horse library under the current working directory.

Integer overflow in the _gd2GetHeader function in gd_gd2.c in the GD Graphics Library (aka libgd) before 2.2.3, as used in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8, allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via crafted chunk dimensions in an image.

Use-after-free vulnerability in libcurl before 7.50.1 allows attackers to control which connection is used or possibly have unspecified other impact via unknown vectors.

The cert_revoke command in FreeIPA does not check for the "revoke certificate" permission, which allows remote authenticated users to revoke arbitrary certificates by leveraging the "retrieve certificate" permission.

The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability.

The net/http package in Go through 1.6 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue.

PHP through 7.0.8 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, as demonstrated by (1) an application that makes a getenv('HTTP_PROXY') call or (2) a CGI configuration of PHP, aka an "httpoxy" issue.

fontconfig before 2.12.1 does not validate offsets, which allows local users to trigger arbitrary free calls and consequently conduct double free attacks and execute arbitrary code via a crafted cache file.

The rds_inc_info_copy function in net/rds/recv.c in the Linux kernel through 4.6.3 does not initialize a certain structure member, which allows remote attackers to obtain sensitive information from kernel stack memory by reading an RDS message.

Heap-based buffer overflow in the opj_dwt_interleave_v function in dwt.c in OpenJPEG, as used in PDFium in Google Chrome before 53.0.2785.89 on Windows and OS X and before 53.0.2785.92 on Linux, allows remote attackers to execute arbitrary code via crafted coordinate values in JPEG 2000 data.

The onReadyRead function in core/coreauthhandler.cpp in Quassel before 0.12.4 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via invalid handshake data.

The ehci_advance_state function in hw/usb/hcd-ehci.c in QEMU allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via a circular split isochronous transfer descriptor (siTD) list, a related issue to CVE-2015-8558.

The read_binary function in buffer.c in pgpdump before 0.30 allows context-dependent attackers to cause a denial of service (infinite loop and CPU consumption) via crafted input, as demonstrated by the \xa3\x03 string.

The _asn1_extract_der_octet function in lib/decoding.c in GNU Libtasn1 before 4.8, when used without the ASN1_DECODE_FLAG_STRICT_DER flag, allows remote attackers to cause a denial of service (infinite recursion) via a crafted certificate.

Buffer overflow in the mipsnet_receive function in hw/net/mipsnet.c in QEMU, when the guest NIC is configured to accept large packets, allows remote attackers to cause a denial of service (memory corruption and QEMU crash) or possibly execute arbitrary code via a packet larger than 1514 bytes.

Buffer overflow in the stellaris_enet_receive function in hw/net/stellaris_enet.c in QEMU, when the Stellaris ethernet controller is configured to accept large packets, allows remote attackers to cause a denial of service (QEMU crash) via a large packet.

Integer overflow in the x86 shadow pagetable code in Xen allows local guest OS users to cause a denial of service (host crash) or possibly gain privileges by shadowing a superpage mapping.

The Verify function in crypto/dsa/dsa.go in Go before 1.5.4 and 1.6.x before 1.6.1 does not properly check parameters passed to the big integer library, which might allow remote attackers to cause a denial of service (infinite loop) via a crafted public key to a program that uses HTTPS client certificates or SSH server libraries.

Multiple XML external entity (XXE) vulnerabilities in the (1) Dom4JDriver, (2) DomDriver, (3) JDomDriver, (4) JDom2Driver, (5) SjsxpDriver, (6) StandardStaxDriver, and (7) WstxDriver drivers in XStream before 1.4.9 allow remote attackers to read arbitrary files via a crafted XML document.

The binary delta decoder in Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a (1) clone, (2) push, or (3) pull command, related to (a) a list sizing rounding error and (b) short records.
