Vulnerabilidades

A flaw was found in Mercurial before 4.9. It was possible to use symlinks and subrepositories to defeat Mercurial's path-checking logic and write files outside a repository.

cext/manifest.c in Mercurial before 4.7.2 has an out-of-bounds read during parsing of a malformed manifest entry.

The mpatch_decode function in mpatch.c in Mercurial before 4.6.1 mishandles certain situations where there should be at least 12 bytes remaining after the current position in the patch data, but actually are not, aka OVE-20180430-0001.

mpatch.c in Mercurial before 4.6.1 mishandles integer addition and subtraction, aka OVE-20180430-0002.

The mpatch_apply function in mpatch.c in Mercurial before 4.6.1 incorrectly proceeds in cases where the fragment start is past the end of the original data, aka OVE-20180430-0004.

Mercurial version 4.5 and earlier contains a Incorrect Access Control (CWE-285) vulnerability in Protocol server that can result in Unauthorized data access. This attack appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in 4.5.1.

An improper authorization vulnerability exists in Jenkins Mercurial Plugin version 2.2 and earlier in MercurialStatus.java that allows an attacker with network access to obtain a list of nodes and users.

In Mercurial before 4.4.1, it is possible that a specially malformed repository can cause Git subrepositories to run arbitrary code in the form of a .git/hooks/post-update script checked into the repository. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically.

Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shell-injection attacks.

Mercurial prior to version 4.3 is vulnerable to a missing symlink check that can malicious repositories to modify files outside the repository

In Mercurial before 4.1.3, "hg serve --stdio" allows remote authenticated users to launch the Python debugger, and consequently execute arbitrary code, by using --debugger as a repository name.

The convert extension in Mercurial before 3.8 might allow context-dependent attackers to execute arbitrary code via a crafted git repository name.

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.

Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a crafted name when converting a Git repository.

Mercurial before 3.7.3 allows remote attackers to execute arbitrary code via a crafted git ext:: URL when cloning a subrepository.

The _validaterepo function in sshpeer in Mercurial before 3.2.4 allows remote attackers to execute arbitrary commands via a crafted repository name in a clone command.

Mercury MR804 Router 8.0 3.8.1 Build 101220 Rel.53006nB allows remote attackers to cause a denial of service (service hang) via a crafted string in HTTP header fields such as (1) If-Modified-Since, (2) If-None-Match, or (3) If-Unmodified-Since. NOTE: some of these details are obtained from third party information.

Unspecified vulnerability in HP TestDirector for Quality Center 9.2 before Patch8 allows remote attackers to modify data via unknown vectors.

Multiple stack-based buffer overflows in Mercury Audio Player 1.21 allow remote attackers to execute arbitrary code via a long string in a malformed (1) .b4s or (2) .pls playlist file.

Stack-based buffer overflow in Mercury Audio Player 1.21 allows remote attackers to execute arbitrary code via a long string in a malformed playlist (.m3u) file.

The Unreal engine, as used in Unreal Tournament 3 1.3, Unreal Tournament 2003 and 2004, Dead Man's Hand, Pariah, WarPath, Postal2, and Shadow Ops, allows remote authenticated users to cause a denial of service (server exit) via multiple file downloads from the server, which triggers an assertion failure when the…

SQL injection vulnerability in func/login.php in MercuryBoard 1.1.5 and earlier allows remote attackers to execute arbitrary SQL commands via the User-Agent HTTP header ($_SERVER['HTTP_USER_AGENT']).

HP Mercury Quality Center (QC) 9.2 and earlier, and possibly TestDirector, relies on cached client-side scripts to implement "workflow" and decisions about the "capability" of a user, which allows remote attackers to execute arbitrary code via crafted use of the Open Test Architecture (OTA) API, as demonstrated by…

Mercurial before 1.0.2 does not enforce the allowpull permission setting for a pull operation from hgweb, which allows remote attackers to read arbitrary files from a repository via an "hg pull" request.

Directory traversal vulnerability in patch.py in Mercurial 1.0.1 allows user-assisted attackers to modify arbitrary files via ".." (dot dot) sequences in a patch file.
