Canonical » Ubuntu Linux » 17.10 : Security Vulnerabilities, CVEs, Published In 2018 (Memory corruption)

curl version curl 7.54.1 to and including curl 7.59.0 contains a CWE-122: Heap-based Buffer Overflow vulnerability in denial of service and more that can result in curl might overflow a heap based memory buffer when closing down an FTP connection with very long server command replies.. This vulnerability appears to have been fixed in curl < 7.54.1 and curl >= 7.60.0.

The Linux Kernel version 3.18 contains a dangerous feature vulnerability in modify_user_hw_breakpoint() that can result in crash and possibly memory corruption. This attack appear to be exploitable via local code execution and the ability to use ptrace. This vulnerability appears to have been fixed in git commit f67b15037a7a50c57f72e69a6d59941ad90a0f0f.

A NULL pointer dereference exists in curl 7.21.0 to and including curl 7.58.0 in the LDAP code that allows an attacker to cause a denial of service

A buffer overflow exists in curl 7.12.3 to and including curl 7.58.0 in the FTP URL handling that allows an attacker to cause a denial of service or worse.

The Squid Software Foundation Squid HTTP Caching Proxy version prior to version 4.0.23 contains a NULL Pointer Dereference vulnerability in HTTP Response X-Forwarded-For header processing that can result in Denial of Service to all clients of the proxy. This attack appear to be exploitable via Remote HTTP server responding with an X-Forwarded-For header to certain types of HTTP request. This vulnerability appears to have been fixed in 4.0.23 and later.

In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to write before the destination buffer leading to a buffer underflow and potential code execution.

In ImageMagick 7.0.8-3 Q16, ReadDIBImage and WriteDIBImage in coders/dib.c allow attackers to cause an out of bounds write via a crafted file.

In ImageMagick 7.0.8-3 Q16, ReadBMPImage and WriteBMPImage in coders/bmp.c allow attackers to cause an out of bounds write via a crafted file.

A use-after-free vulnerability can occur when script uses mutation events to move DOM nodes between documents, resulting in the old document that held the node being freed but the node still having a pointer referencing it. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.

A use-after-free vulnerability can occur when deleting an input element during a mutation event handler triggered by focusing that element. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.

The getImageData function in the ImageBufferCairo class in WebCore/platform/graphics/cairo/ImageBufferCairo.cpp in WebKit, as used in WebKitGTK+ prior to version 2.20.3 and WPE WebKit prior to version 2.20.1, is vulnerable to a heap-based buffer overflow triggered by an integer overflow, which could be abused by crafted HTML content.

Liblouis 3.5.0 has a stack-based Buffer Overflow in the function compileHyphenation in compileTranslationTable.c.

Liblouis 3.5.0 has a stack-based Buffer Overflow in the function includeFile in compileTranslationTable.c.

Liblouis 3.5.0 has a stack-based Buffer Overflow in the function parseChars in compileTranslationTable.c, a different vulnerability than CVE-2018-11440.

Liblouis 3.5.0 has a Segmentation fault in lou_logPrint in logging.c.

Exiv2 0.26 has a heap-based buffer overflow in getData in preview.cpp.

Liblouis 3.5.0 has a stack-based Buffer Overflow in the function parseChars in compileTranslationTable.c.

An issue was discovered in libjpeg 9a. The get_text_rgb_row function in rdppm.c allows remote attackers to cause a denial of service (Segmentation fault) via a crafted file.

An issue was discovered in libjpeg 9a. The get_text_gray_row function in rdppm.c allows remote attackers to cause a denial of service (Segmentation fault) via a crafted file.

An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. ext/ldap/ldap.c allows remote LDAP servers to cause a denial of service (NULL pointer dereference and application crash) because of mishandling of the ldap_get_dn return value.

An issue was discovered in LibRaw 0.18.9. There is a stack-based buffer overflow in the utf2char function in libraw_cxx.cpp.

WriteEPTImage in coders/ept.c in ImageMagick 7.0.7-25 Q16 allows remote attackers to cause a denial of service (MagickCore/memory.c double free and application crash) or possibly have unspecified other impact via a crafted file.

The unimac_mdio_probe function in drivers/net/phy/mdio-bcm-unimac.c in the Linux kernel through 4.15.8 does not validate certain resource availability, which allows local users to cause a denial of service (NULL pointer dereference).

An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FormatSupport/WEBP_Support.cpp does not check whether a bitstream has a NULL value, leading to a NULL pointer dereference in the WEBP::VP8XChunk class.

The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.
