Summary

An issue was discovered in GNU patch before 2.7.6. Out-of-bounds access within pch_write_line() in pch.c can possibly lead to DoS via a crafted input file.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionThe remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has patch packages installed that are affected by multiple vulnerabilities: - An issue was discovered in GNU patch before 2.7.6. Out- of-bounds access within pch_write_line() in pch.c can possibly lead to DoS via a crafted input file. (CVE-2016-10713) - A double free exists in the another_hunk function in pch.c in GNU patch through 2.7.6. (CVE-2018-6952) - GNU patch through 2.7.6 is vulnerable to OS shell command injection that can be exploited by opening a crafted patch file that contains an ed style diff payload with shell metacharacters. The ed editor does not need to be present on the vulnerable system. This is different from CVE-2018-1000156. (CVE-2019-13638) - do_ed_script in pch.c in GNU patch through 2.7.6 does not block strings beginning with a ! character. NOTE: this is the same commit as for CVE-2019-13638, but the ! syntax is specific to ed, and is unrelated to a shell metacharacter.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link (s) in the References section. The patch program applies diff files to originals. The diff command is used to compare an original to a changed file. Diff lists the changes made to the file. A person who has the original file can then use the patch command with the diff file to add the changes to their original file (patching the file). Security Fix(es) : * patch: Out-of-bounds access in pch_write_line function in pch.c (CVE-2016-10713) * patch: Double free of memory in pch.c:another_hunk() causes a crash (CVE-2018-6952) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

    descriptionThis update for patch fixes several issues. These security issues were fixed : - CVE-2018-1000156: patch: Malicious patch files cause ed to execute arbitrary commands (bsc#1088420). - CVE-2014-9637: Prevent DoS by remote attackers (memory consumption and segmentation fault) via a crafted diff file (bsc#914891). - CVE-2016-10713: Prevent out-of-bounds access within pch_write_line() that could have lead to DoS via a crafted input file (bsc#1080918). - CVE-2010-4651: Fixed a directory traversal bug (bsc#662957) : Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionAn update for patch is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link (s) in the References section. The patch program applies diff files to originals. The diff command is used to compare an original to a changed file. Diff lists the changes made to the file. A person who has the original file can then use the patch command with the diff file to add the changes to their original file (patching the file). Security Fix(es) : * patch: Out-of-bounds access in pch_write_line function in pch.c (CVE-2016-10713) * patch: Double free of memory in pch.c:another_hunk() causes a crash (CVE-2018-6952) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

    NASL idEULEROS_SA-2019-2645.NASL
    descriptionAccording to the versions of the patch package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - An issue was discovered in GNU patch before 2.7.6. Out-of-bounds access within pch_write_line() in pch.c can possibly lead to DoS via a crafted input file.(CVE-2016-10713) - do_ed_script in pch.c in GNU patch through 2.7.6 does not block strings beginning with a ! character. NOTE: this is the same commit as for CVE-2019-13638, but the ! syntax is specific to ed, and is unrelated to a shell metacharacter.(CVE-2018-20969) - GNU patch 2.7.1 allows remote attackers to write to arbitrary files via a symlink attack in a patch file.(CVE-2015-1196) - GNU patch 2.7.2 and earlier allows remote attackers to cause a denial of service (memory consumption and segmentation fault) via a crafted diff file.(CVE-2014-9637) - GNU patch through 2.7.6 is vulnerable to OS shell command injection that can be exploited by opening a crafted patch file that contains an ed style diff payload with shell metacharacters. The ed editor does not need to be present on the vulnerable system. This is different from CVE-2018-1000156.(CVE-2019-13638) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
