Category:Security:SSA: Difference between revisions

Slackware has recently started to be inactive. At the same time, a number of security issues have been found in various components. This page aims at listing them in order to help everyone know which components have known vulnerabilities.

The list below is provided as-is. It is meant to be as good as possible but we can't guarantee anything. It is sorted by slackware categories: a/, ap/, d/, ...

A more comprehensive effort might appear at some point in the future (binary packages?) but this is currently only a list of packages and their CVEs when applicable and useful. In some cases, we consider pointing out a specific CVE is not useful because of the number of issues (i.e. get the last version; e.g. mozilla-*).

The CVEs are typically listed as follow: ${SUMMARY}

• Fix:
  • Fixed upstream on: ${DATE}
  • Available in version: ${UPSTREAM_VERSION_WITH_FIX} (-current ${VERSION_IN_CURRENT}; -stable: ${VERSION_IN_13_37})
  • Upstream commit: ${URL_TO_THE_SPECIFIC_FIX_COMMIT}

CVE-2011-3170 (Execute Code, Overflow) affected: current, 13.37 and all before

The gif_read_lzw function in filter/image-gif.c in CUPS 1.4.8 and earlier does not properly handle the first code word in an LZW stream, which allows remote attackers to trigger a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted stream, a different vulnerability than CVE-2011-2896.

CVE-2011-2896 (Execute Code, Overflow) affected: current, 13.37 and all before

The LZW decompressor in the LWZReadByte function in giftoppm.c in the David Koblas GIF decoder in PBMPLUS, as used in the gif_read_lzw function in filter/image-gif.c in CUPS before 1.4.7, the LZWReadByte function in plug-ins/common/file-gif-load.c in GIMP 2.6.11 and earlier, the LZWReadByte function in img/gifread.c in XPCE in SWI-Prolog 5.10.4 and earlier, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows remote attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2895.

The SecureRandom.random_bytes function in lib/securerandom.rb in Ruby before 1.8.7-p352 and 1.9.x before 1.9.2-p290 relies on PID values for initialization, which makes it easier for context-dependent attackers to predict the result string by leveraging knowledge of random strings obtained in an earlier process with the same PID.

CVE-2011-0188 (Denial Of Service, Execute Code) affected: current, 13.37 and all before

The VpMemAlloc function in bigdecimal.c in the BigDecimal class in Ruby 1.9.2-p136 and earlier, as used on Apple Mac OS X before 10.6.7 and other platforms, does not properly allocate memory, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving creation of a large BigDecimal value within a 64-bit process, related to an "integer truncation issue."

libxml2

CVE-2011-1944 (Denial Of Service, Execute Code, Overflow) affected: current, 13.37 and all before

Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions.
